I tried to do simulation of MCB example design on sp601.

I can run it on chip scope.

I am running isim simulator.

I have been trying for almost 3 days.

I could see values for other signals but for data bus.. 
zzzzzzzzz.(except some times i see 000..fff)

I dont know what i am doing wrong...

Is the version of simulator matter?

VHDL design with verilog memory model matters???

What example? Can you send a link to the example?

>I can run it on chip scope.
Huh. Chipscope is no simulator. Chipscope is a debugging tool.

>I am running isim simulator.
Ok. Fine.

>I could see values for other signals but for data bus..

What did you expect on your data bus?
"Z" means tristate. It's normal on busses that are driven from more than 
on driver.

>I dont know what i am doing wrong...
I don't know what you expect.

>Is the version of simulator matter?
No, not really.

>VHDL design with verilog memory model matters???
No. Isim should be fine for that.
