Where is the verilog model for SRAM?

Where is the verilog model for SRAM?
I need a verilog SRAM model such as IS61LV51216 used in ModelSim, but
I can't find it in ISSI website, who can help me ?
Thank you very much!

It is on the ISSI web site. It took me less than 30 seconds to find
the following, and that was using a crummy search engine!

================================================== ==========================
// IS61LV51216 Asynchronous SRAM, 512K x 16 = 8M; speed: 10ns.
// Please include "+define+ OEb" in running script if you want to
check
// timing in the case of OE_ being set.

// `define OEb
`timescale 1ns/10ps

module IS61LV51216 (A, IO, CE_, OE_, WE_, LB_, UB_);
<snip>
================================================== ==========================

Google - it's not just for abusing usenet, it's good for searching too.

O.K. Your Google is better than mine?

The best I could do (searching only on ISSI.com) was a .pdf document
with
the paragraph:

"ISSI provides simulation models for each SRAM, DRAM and ASSP part
manufactured.
These models are revised as new device and technologies are developed.
Models for logic
products may be requested; they are developed as needed. Models can be
obtained by
contacting ISSI FAE department."

Care to post the link to the model you found?

Regards,
Gabor

I too can only fine the pdf file. Verilog model link is not there for
above part number.

Hint #2: Look for the word "verilog" on the page Mike is sending you
to.

I think that was obvious, the question is where is the file
for the particular device in question, which does not have
the "Verilog" link next to it in the table. I'm sure that
a little work with the datasheet (for timing and address
width) and an existing model from another part could give
you a working model, but it is always preferable to work
from a known good model for the actual part, especially if
you are trying to verify functionality of new code.
