The condition is tested before wach iteration.< &ptable. If the keyword wait is not followed . for example: process begin a <= '1'; wait for 5 ns; a <= '0'; b . So, you are only almost right that they are equivalent: during simulation the initialization is different.
Implementing infinite wait in shell scripting
The synthesizer does not care about the testbench, it tries to create a piece of hardware that would be equivalent to your loop and would work for any possible input. The reason is that no data are committed and no Update processing is triggered by the BAPI_TRANSACTION_COMMIT if a COMMIT WORK was executed before. Resuming the process or procedure depends on meting the condition (s) specified in the wait statement.Refer to this Answer Record for help resolving a HDLCompiler:634:Net does not have a driver warning.

Synthesisable alternative to the wait statement in VHDL
It can be used in both synthesizable and non-synthesizable code, but is more often used in test benches and models. Expected behaviour I expect to get a warning about simulation time not advancing, especially when there's a wait statement on said process. The condition is tested .My while loop does not exit when Ctrl+C is pressed.A wait statement suspends a process until Foundation Express detects a positive-going edge or negative-going edge on a signal. Lestard's template is the one I would use. Suspension and subsequent resumption of a process occurs in a wait statement. Unfortunately it is apparently not smart enough to detect that this loop always terminates in at most 3 iterations (not .This may sound trivial, but I'm pretty sure this question hasn't been asked, or at least I can't find it.
