Event Origin

Before Using Event Origin

Event Origin requires that VirSim compile the Verilog source so it can

obtain information about the design that is not available from the

simulator or vpd file. Source and compile options used must match

those that were used when the simulation was run. If the Verilog code

has not already been compiled, you will be prompted for the source

by the Load Sources Dialog box when Event Origin is selected.

If line trace data was saved in the VCD+ file, the Event Origin function

will point to the line of source that caused the transition. It also uses

this data to eliminate possible drivers that were not actually executed

at the time the event occurred.

Note:

Older VCD+ files are missing some information to allow driver

elimination. To use this feature you should create your VCD+ files

using a VirSim 3.0 or later PLI.

Where You Can Use Event Origin

Event Origin is allowed at various places in the different

windows. When event origin is not allowed it is not sensitive,

which is due to one of the following:

1. The window is linked to SIM. Event origin is not allowed when the

window is linked to a simulator. Unlink from SIM and then try event

origin.

2. A single net can not be determined from the current mouse

location (expressions are not allowed).
