To do this, perform the following steps: HSPICE decks are used to perform highly accurate simulations by describing the physical properties of all aspects of a circuit precisely. Edit the properties on the schematic symbol to match the Part definition. There is a list of Command Line commands in the DxDesigner Reference Manual, many of these will work as keystrokes, but not as mouse strokes.
The board designer can request such changes to improve the board routing and layout. Do not apply this method of hold-time analysis to source synchronous buses. If the Xpedition Style Keybindings checkbox is unchecked, DxDesigner will use the key bindings in vdbindings.
You can edit the preview graphic of the symbol in the Symbol Pins tab. Welcome to the wonderfull world of MentorGraphics, where you have to pay for even the basic features. Synthesized tuning, Part 2: Fully customizable —Unless connected to an arbitrary board description, the description of the board trace model must be customized in the model file.
What is the function of TR1 in this circuit 3. For current FPGA families, the maximum recommended voltage corresponds to the fast corner, while the minimum recommended voltage corresponds to the slow corner.

Generic components can cause some problems with your design. A default board description is included, and a default simulation is set up to measure rise and fall delays for both input and output simulations, which compensates for the double counting problem. You can set the function of the dual-purpose pins by selecting a value for a specific pin in the Dual-purpose pins list. You can set device and pin options and verify important design-specific data in the Device and Pin Options dialog box, including options found on the GeneralConfigurationUnused PinDual-Purpose Pinsand Voltage pages.
The simulation analysis block is set up to measure double-counting corrected delays. This folder will become the parent folder for the whole project 4. The inputs and outputs of the FPGA are defined, and required board routing topologies and constraints are known.
Title for Topic
BoardSim is a post-layout tool that you use to analyze existing board routing. Finally, the Fitter Device Options report summarizes some of the settings made in the Device and Pin Options dialog box. The Device dialog box provides project-specific device information, including the target device and any migration devices you specify. These are caused by dxdezigner replacement, where trace ends do not exactly match the pad center.

With these tools, you can set up and run accurate simulations quickly and acquire data that helps guide your FPGA and board design. To create a symbol with the Symbol wizard, follow these steps.
These models can be changed as much as required to see how adjustments improve timing or signal integrity and dxddsigner with the design and routing of the PCB. When finished, the Expedition design will be located in the folder created earlier.
Because board-level simulation is important to verify, you should check for potential signal integrity issues. This information is used as part of the double-counting correction circuitry contained in the simulation file. After the translation has finished, now is a good time to create a zipped up copy of the results as a backup.
This includes a trace model, termination resistors, and, for output simulations, a receiver model. Corrected statement about timing simulation and double counting. The FPGA or ASIC designer initially creates signal and pin assignments, and the board designer must correctly transfer these assignments to the symbols in their system circuit schematics and board layout. Your new project is in the specified location and consists of the following files: On the View menu, click Package to view thumbnails of all the part sections.
You can add series or parallel termination, specify the transmission line length, and set the value of the far-end capacitive load.
In addition to circuit simulation, circuit board schematic creation is one of the first tasks required when designing a new PCB. Most component manufacturers, including Intelprovide IBIS models for free download and use in signal integrity analysis simulation tools.
With the default simulation configured by the HSPICE Writer, you can view the simulated waveforms at both the source and dxdeskgner in input and output simulations.
You can also create hierarchical manuap to facilitate design reuse and team-based design using the Cadence Allegro Design Entry CIS software.
This document contains information that is proprietary to Mentor Graphics Corporation. This chapter is intended for FPGA and board designers and includes details about the concepts and steps involved in getting designs simulated and how to adjust designs to improve board-level timing and signal integrity. When you are ready, click Split. Close Library Manager 6.
Integrating with DxDesigner
If you select a part that is split into sections, you can select the section to place from the Part menu. Minor update of Pin Planner description for task and report windows. This docuument describbes the recomm mended proccess for transslating a schematic and board b and inntegrating thee two. This may cause the plane shape to become Net0 and thus unconnected from the pins.
Edit the Part definition to match the schematic symbol properties. Open this file in a text editor, like Microsoft Wordpad. You can add symbols to an existing library or you can create a new library specifically for the symbols generated from your FPGA designs.
To view the new sections of the part, double-click the part. If any layer modifications are required, please refer to the Configuration Guide. Government subcontractor is subject to the restrictions set forth in the license agreement provided with the software pursuant to DFARS
