The Inclusive Organization Framework, a cutting-edge diagnostic tool developed by IBIS, gives organizations a clear appraisal of how thoroughly they have embedded Diversity, Equity and Inclusion DEI in their policies, procedures, and programs, and what changes are needed to ensure DEI success. The Framework, which is systemic, is organized into three traditional categories:. Radiating outward, each level expands and builds on the smaller circle s it encompasses. This tool also informs how we assess an organization, utilizing the following solutions:.
Option 1: Basic assessment: Self-administered online assessment tool with automated reporting and recommendations. Outcomes: The organization receives an automated report with primary recommendations. The report enables the organization to:. In addition to the basic online assessment in Option 1, IBIS performs a thorough analysis of representative documents, policies, and programs; interviews senior leaders and key stakeholders; conducts focus groups across demographics; and administers an online employee DEI perception survey.
Outcomes: IBIS presents a comprehensive report with findings, tailored recommendations, suggested priorities, and metrics to measure progress. In addition to the Option 1 outcomes, Option 2 also enables organizations to:.
While all phases of our engagement with IBIS so far have been exceptional, we have been especially impressed with the data gathering and analysis aspects. Through interviews, focus groups and a comprehensive survey, IBIS was able to gather a treasure-trove of information. We gained significant insights from the data. This has provided us with an extremely strong foundation from which we can confidently base our decisions to further our Diversity and Inclusion initiative.
In addition to the Option 1 outcomes, Option 2 also enables organizations to: Investigate disparities in employee experiences across demographic groups Identify specific policies, programs and practices which may be inhibiting DEI in 14 key organizational areas Develop and implement changes to align with industry best and emerging practices.I hope you had a chance to go through and digest the content from the earlier post, where we discussed the basics of Signal integrity Simulations, and the models required to run them.
If you haven't, I would highly recommend going over the post here before proceeding with this entry. This is used for Pre-Layout simulations and is an early simulation tool in the design cycle.Adding Third-Party Models to LTspice IV
It is used to evaluate what-if scenarios and to help define board parameters and routing guidelines. Because it uses the layout file containing the routing constraints along with information on the adjacent nets routing and distance, the simulations will be highly accurate. Any violations or changes required can be explored in LineSim and fed back into the layout before signing off on the final PCB to be fabricated. During this series, LineSim and Boardsim will be used as and when needed, depending on the topic being discussed.
Save the schematic setup. The RX waveform Green and TX waveform Red do not have clean transitions and these will be discussed in more detail in later topics in the series.
Select the necessary settings for the model. This will complete the schematic. This will open up the Digital Oscilloscope window.

This places the Simulation probe at the pin and represents what you would see in a lab oscilloscope if you physically probed at the pin on the board. This places the Simulation probe inside the die and represents what the die sees, which cannot be probed on the board. The layer stackup for the PCB needs to be defined for the dielectric material, metal type, arrangement of signal and plane layers in a board among other items. Setting this up before running simulations helps to mimic the PCB, along with various characteristics such as trace impedance, trace separation and other parameters.
As seen in the above figure, the Editor has various tabs and a quick description of the tabs. Dielectric: Define the dielectric characteristics of the stackup such as technology, loss tangent, and thermal conductivity. There is an option to calculate the dielectric constant for the metal layer from surrounding dielectric layers. Z0 Planning: Define the characteristic impedance of the stackup.
This planning tab is one of the most useful tabs as it enables you to calculate the optimal data when you need a specific target impedance for single and differential pair traces.
Custom View: Used to set up a customized view of the spreadsheet information derived from the other tabs and to tweak per user preference. There are various methods to set the impedance in the stackup editor, however we will use the Metal tab to quickly set the required impedances. This enables automatic characteristic impedance calculation by the tool based on the stackup.Over-voltage Protection Module to handle Over-voltage operation up to 5.
UltraSoC and Agile Analog collaborate to detect physical cyber attacks. Embedded Software Unit Testing with Ceedling. Imagination's Fate. CEO and execs to resign if China takes control of Imagination. It is actually specification for data format which represents the analog behavior of various IO buffers. The experiment of using I-V curves based buffer models for simulations by Intel became a huge success.
But, since the users use tools from various tool vendors, it was agreed upon by several EDA tool vendors for a common, tool-independent behavioral model format. As it was felt conceivable to model CMOS buffer using edge rates and I-V curves, above basic building blocks were construed to suffice the modeling of the buffers, though at the later stages many new items were introduced into the IBIS model.
In the above figure, the leftmost block is the logic block which controls the rest other blocks to put the buffer into receive, drive high or drive low or tri-state mode. As seen in the figure, the basic IBIS model consists of four I-V curves, two ramp numbers V-t curvedie capacitance and package model.
Moreover, when there is power supply noise the simulator is not required to recalculate the GND relative voltages w.
A buffer usually has three different modes of functioning like receive mode, drive high and drive low mode. So what exactly the I-V curves contain for each mode? This includes the current of pullup and pulldown structures and any other dynamically switching structures. It is to be noted that the I-V curves during the driving mode already contain the static current present in the receive mode.
It contains information about the edge rate i. While tabulating the data for these tables, package effects are excluded. An IBIS file starts with a header section, the details of which are shown in the tree-structure of Figure 2. Again, the I-V curves range is based upon transmission line theory. However, it has given freedom to the model makers to select any points best suited to describe the shape of the curve i.IBIS models are commonly used for analysis and design of high-speed printed circuit boards.
The IBIS driver output models provide the waveform as it appears at the output pin on an IC for a given loading condition. The receiver input model provides the nonlinear terminating impedance as presented by the IC pin. The pull-up driver models the characteristic when driven high or towards the power supply voltage. A power supply clamping diode is connected between output and power supply ports. The ground clamping diode between the output and ground ports prevents any voltage transition going below ground voltage.
There are two kinds of pin package parasitics: individual pin parasitics and global defaults. Statistically, device characteristics deviate due to variations in device operation temperature and variations and fluctuations in the underlying fabrication processes. Three different characteristic values typical, minimum and maximum values are available to reflect these deviations in device performance.
Please note that the IBIS translator allows you to add multiple components in the same design kit. To identify the different IC component, you can select different bitmap captions for different. Select the IBIS component and use it in your design.
The ground port labeled Vg provides the ground connection. Not all the keywords defined in the IBIS specifications are supported. The following table shows the support IBIS model types and their bitmaps representation:. The parameters listed below have three different characteristic values typical, minimum and maximum and can be selected by the user to represent a typical, fast, or slow device. The parameters listed below specify average pin package parasitic. They have three characteristic values- typical, minimum and maximum.
The default is typical. In general, these parameters should all be set to the same value. The actual numeric values to which the characteristic values correspond are defined in the. The IBIS models can be edited on screen to change the pin number. Once the pin number is selected, all the model parameters are automatically selected. Select only the pin number and the type of model parameters Minimum, Typical, or Maximum. Other parameter numeric values for example, mode file, pin parasitics and the voltage range equivalent circuit will be automatically selected.
The components in Buffer Library provide easy-to-use sub-circuits for high-speed simulation. Use the impedance optimizer to determine transmission line characteristic, given the desired line impedance. The buffer splits the input to two output ports and may be used to increase the number of inputs available from the pulse and step meter simulation component, or to split other sources. Delay may be added to each output signal.
The port impedance is used to match the port impedance to the signal source. The buffer splits the input to four output ports and may be used to increase the number of inputs available from time domain sources. The port impedance is used to match the port impedance of the signal source. The buffer splits the input to eight output ports and may be used to increase the number of inputs available from time domain sources.
The octal pulse generator provides a convenient method of connecting multiple sources to multilayer lines and components. It is based on the time domain pulses voltage source, VTPulse. All the eight sources share the same parameter settings. The octal load provides a convenient method of inserting a load to multilayer lines and components. In addition to load impedance, you can specify capacitance to ground.The issue-based information system IBIS is an argumentation -based approach to clarifying wicked problems —complex, ill-defined problems that involve multiple stakeholders.
IBIS guides the identificationstructuringand settling of issues raised by problem-solving groups, and provides information pertinent to the discourse. Subsequently, the understanding of planning and design as a process of argumentation of the designer with himself or with others has led to the use of IBIS in design rationale  where IBIS notation is one of a number of different kinds of rationale notation.
The basic structure of IBIS is a graph. It is therefore quite suitable to be manipulated by computer, as in a graph database. The elements of IBIS are: issues questions that need to be answeredeach of which are associated with answered by alternative positions possible answers or ideaswhich are associated with arguments which support or object to a given position; arguments that support a position are called "pros", and arguments that object to a position are called "cons".
IBIS elements are usually represented as nodesand the associations between elements are represented as directed edges arrows. InDouglas E. Issue-Based Information Systems are used as a means of widening the coverage of a problem. By encouraging a greater degree of participation, particularly in the earlier phases of the process, the designer is increasing the opportunity that difficulties of his proposed solution, unseen by him, will be discovered by others.
Since the problem observed by a designer can always be treated as merely a symptom of another higher-level problemthe argumentative approach also increases the likelihood that someone will attempt to attack the problem from this point of view.
Another desirable characteristic of the Issue-Based Information System is that it helps to make the design process 'transparent'. Transparency here refers to the ability of observers as well as participants to trace back the process of decision-making. IBIS notation is used in issue mapping,  : ix an argument visualization technique closely related to argument mapping.
Issue mapping is the basis of a meeting facilitation technique called dialogue mapping. The facilitator listens to the conversation, and summarizes the ideas mentioned in the conversation on the shared display using IBIS notation, and if possible "validates" the map often by checking with the group to make sure each recorded element accurately represents the group's thinking. A dialogue map does not aim to be as formal as, for example, a logic diagram or decision treebut rather aims to be a comprehensive display of all the ideas that people shared during a conversation.
Rittel's interest lay in the area of public policy and planning, which is also the context in which he and his colleagues defined wicked problems. When Kunz and Rittel's paper was written, there were three manual, paper-based IBIS-type systems in use—two in government agencies and one in a university.
A renewed interest in IBIS-type systems came about in the following decade, when advances in technology made it possible to design relatively inexpensive, computer-based IBIS-type systems. Noble completed a computer-supported IBIS program as part of his doctoral dissertation. Since the mids, there has been a renewed interest in IBIS-type systems, particularly in the context of sensemaking and collaborative problem solving in a variety of social and technical contexts.
