Complex digital ICs visual simulation?

[Michael]

Hi there!

If I e.g. place a RAM component into MultiSim, will it simulate
it? I.e. can I (using switches and hex displays) write on the
RAM and then read back? Is the IC really simulated, or it's just
a graphic symbol?

If so, is there any other program that will do it?

Thanks!

In principle yes. This depend on if you can figure out how to drive
multisim.

Thanks for your reply. I managed to enter data into the simulated
RAM via switches, and read it back correctly using hex displays.

But, ain't it possible to directly load a binary file into the
simulated RAM (or EPROM) to initialize its values?

I'd like to design a very simple CPU, and having to load the program
each time via switches is, to say the very least, tedious.

Thanks!

Since you are posting in the Verilog newsgroup, I assume you're using
Verilog for simulation. You can use $readmemh and $readmemb system tasks to
initialize memory in Verilog.
