[SOLVED] Is it possible to have a process inside another process? (VHDL)

[555lin]

I need to a certain component to be executed based on a
set condition, for example when the start pulse is excited.
What code should I use?

P.S. A component is a concurrent statement using "when" operator

i think u can use if generate statement..

Re: VHDL question

I used the if (Start='1') generate... statement but
the error message says:result of operator = is not static.
But Start cannot be static because it's a start pulse.



Is it possible to have a process inside another process?

Re: VHDL question

hI ALL..

If its possible to use process inside another process, i cant find any reason to use such hierarchical process....

Can anyone tell me a reason for that??

Re: VHDL question

I think you can you an enable signal for that component... for all the process you use in that component use an if statement at the begining of the process... if enable is high then all the statements could be executed inside the if else the ouputs can either be tristated or zeros...
