Xilinx 7 series PCIe core models vs. Icarus Verilog

We are looking for simulation models for the Xilinx 7 series
FPGA PCIe core. We use Icarus Verilog models extensively, but
the models that Xilinx provides are encrypted, so locked in to
a small set of other simulators. We are hoping that we are not
the only ones with this problem and we can share simulation
models for their core.

The PCIe embedded hard block is a very complicated design and the
simulation models are released as encrypted models to protect the IP.
Simulation is supported in the free Xilinx iSim simulator as well as
ModelTech and I belive VCS simulators.

There is no support for Icarus.

That is very awkward for us since we use a fair amount of VPI
code in our system level simulations. We are basically being forced
to either come up with our own simulation of the PCIe hard core,
or port our simulation environment to a "blessed" simulator.

At one time I talked with some of your engineers about adding the
necessary encryption support into Icarus Verilog, but it was not
clear to me which encryption method you used, and whether it would
have been viable to have an open source implementation of it. I
think we concluded no.

Move away from SmartModels was primarily due to a lack of continuing
support from Synopsys for the latest OS and simulator versions.

The SecureIP models are supported in a wide range of simulators as the
answer record shows.

Support for operating systems beyond Linux and Windows are not on our
product roadmaps.
