File simulatormodule.c¶

Python extension to provide access to the simulator.

Uses GPI calls to interface to the simulator.

Callback Handling

Handle a callback coming from GPI

GILState before calling: Unknown

GILState after calling: Unknown

Makes one call to TAKE_GIL and one call to DROP_GIL

Returns 0 on success or 1 on a failure.

Handles a callback from the simulator, all of which call this function.

We extract the associated context and find the Python function (usually cocotb.scheduler.react) calling it with a reference to the trigger that fired. The scheduler can then call next() on all the coroutines that are waiting on that particular trigger.

TODO:

Tidy up return values
Ensure cleanup correctly in exception cases
