Foundation Simulator: End of time error


Keywords: End of time, Foundation, simulator, precision

Urgency: Standard

General Description:

The Foundation simulator uses a 32 bit integer to track
the number of clock periods. This results in approximately
four billion clock periods that can be tracked. When this
integer overflows, an 'End of time error' is reported.


This error can be fixed by changing the 'Simulation Precision'.
This can be done with the following steps:

* In the Logic Simulator, select Options->Preferences.
* In the tab section 'Simulation', change the 'Simulation
Precision' to a larger number. Click on 'OK'.

The design can now be simulated.
