Hi,

simulation of Xilinx blockram is no problem.
You only need the Xilinx unisim library for this
(\Xilinx\vhdl\src\unisims\ )
=> You must compile this library with modelsim
and include to your project.

Hi

I have a problem in simulating a memory block (VHDL-written control
unit and BlockRAM for Virtex II). BRAM is instantiated as shown below.
The problem for me is that the VHDL description of BRAM is not
available. The question is that

- Can we simulate it in modelsim SE 6.0c?
- In case only the BRAM-instantiation is enough to simulate and
synthesize, is it meaning that simulator/synthesis tool(XST) has the
library?

Thankyou in advance for comment
