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??? .

>I tried to do simulation of MCB example design on sp601. 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.. >zzzzzzzzz.(except some times i see 000..fff) 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. Duke
