Keywords: simulator, stopped
I encounter the following errors when I run a simulation using ISim,
Finished circuit initialization process.
at 607800 ns: Error: read 100 us;ization phasefor ADS1282 to the factory defaults a unit is expected
at 607800 ns: Error: TEXTIO read: empty line is read
ERROR: at 607800 ns: Negative wait time (-2147483647 ps) on line 59 in file "tb_test.vhd"
ERROR: In process tb_test.vhd:42
The error appears to be associated with the following variable syntax:
wait for delay;
where 'delay' is defined by
variable delay : time;
How can I resolve this error?
This is a known issue in all updates of ISE Design Suite 11. This issue is currently under investigation in order to better address this condition in a future release of the ISE Simulator.
To work around this issue in ISE Design Suite 11, change the variable type from 'time' to 'integer'.
