[SOLVED] Problem in writing WHEN statement in vhdl

[er.akhilkumar]

Hello All,

Can we execute two commands in one when statement as following

A <= B WHEN C = '1' ELSE
'0';

In the above code if else condition comes I want that an assertion shall also fire. Can we execute two statements in one when statement. Actually I don't want to use PROCESS for implementing this logic.

Please provide your comments. thanx

Why don't you want to use a process? That sounds pretty arbitrary.

You could also use two separate WHEN statements, right?

Do you actually mean an assert statement? It don't understand how it's related to the conditional assignment? It woul be placed as an concurrent independent statement.

I can write process also...bt I want to write small code...can we write two statements in one WHEN statement?

Consider it as an experiment

Why don't you tell the exact WHEN construct you imagine? In my view, the syntax rules for the conditional assignment statement are pretty clear.

Writing 'small code' has NO bearing on the final output; you're ultimately creating hardware NOT writing software. 'Small code' is usually hard-to-understand code. I think the answer to your question is:


No, you can't have two assignments in a single WHEN statement.
