i am new here. I have a problem as below when i do my design simulation:
Simulation stopped via $stop(1) at time 40384446008 PS + 2
how could this happens? thanks!
and my timescale is 1ns/10ps
Hi dzkxybxFrom the limited info which you had provided, it is very hard to guess the cause of the problem. If you are not using the latest version of ncverilog, would you please re-try using the latest version and see if the same problem occurs?Best regardsQuek
In reply to Quek:
The limit for some considerable time has been about 9223 seconds - and you're hitting a limit much less than that.
Are you using some prehistoric version of ncverilog? What does "ncverilog -version" say?
e.g. simulating "ncverilog testmax.v" where testmax.v is:
`timescale 1ps/1fsmodule top;reg a;initial a=1;always #100000000000 begin a=~a; $strobe($time,,"a=%b",a);endendmodule
9223368439474176 a=0 9223369655226368 a=1ncsim: *E,TRTOVF: simulated time overflow. File: ./testmax.v, line = 9, pos = 7 Scope: top Time: 9223370870978560 PS + 0./testmax.v:9 always #100000000000 begin
