Mentor Graphics Corporation
Xilinx and Mentor Graphics have a broad alliance that delivers best in class solutions for all users of programmable logic. This ranges from HDL simulation and synthesis to board level design and verification.
Building a working system today requires knowledge of a more than just digital logic.
The resources on this page are designed to give you everything you need to achieve reliable system-level designs with Xilinx FPGAs on the first try.
Signal Integrity (SI) Fundamental Tools and Models
Xilinx provides an extensive collection of documentation and tools for simulation. We support both IBIS and encrypted HSPICE models and design kits:
PCB Design Tools
Feature size reduction and the need for reduced power consumption have driven core voltages down from the old standard of 3.3V to the 0.9V range. This change in voltage and signal frequency content requires us to use new design practices that take into account electrical effects that could previously be ignored.
