Honored ContributorThe Simulate - Runtime Option, lets me define a default Run time of say 1us. Then upon Simulate - Start simulation, the view changes, goes to Simulate and The Run Length can be checked, it still is 1us. Upon Run -All, the executed time ends at 10ns, coincidental the cycle time of the simulation.
I somehow wasn't able to find the proper way to set the end time. Rene
Honored ContributorIt will stop automatically if there is not more similation to run (eg. your clock has stopped clocking).
Honored ContributorNaa. It didn't even start. It stops after 10ns, and I have a cycle time of 10ns.
Honored Contributorcould it be stuck in an infinite loop?
can you post some source code?Honored ContributorI'm a couple steps further. Indeed the simulation runs until no changes occur. Meaning I have to gate the clock like :
-- Clock Generator process begin clock <='0'; wait until Reset = '1'; wait for clockcycle; while Reset = '1' loop clock <= '1'; wait for clockcycle/2; clock <= '0'; wait for clockcycle/2; end loop; wait; end process; The gate process : -- Reset process begin Reset <= '0'; wait for Clockcycle; Reset <= '1'; wait for EndOfTime; Reset <= '0'; wait; end process; Otherwise it runs forever. Clearly ignoring my wish with the End Time. And even stranger, I have to set the stuff up with a reset = 1 otherwise it also runs forever without a result. -- main begin data <= "00000011"; latch <= '1'; cnten <= '1' ; Reset <= '1'; -- must be 1 here !!! Now, at least I get a simulation going... Thanks a lot this far.Honored Contributoryou cannot assign reset inside and outside the process. This will cause reset to be 'X'
