Reset Textio input file?

[Balázs Sallay]

Hello everyone,

I would like to know if there is a way to restart reading
from a stimulus file other than restarting the simulation.

I am doing mass fault simulation with the faults injected
by simulator commands. Since the simulated chip
needs no VHDL-level initialization, I could go on without
restart (which takes a lot of time), but I cannot manage
the stimulus file.

Any help appreciated,

Balazs

It's unclear whether the stimulus file is read by your VHDL model or
by the simulator.

If the model is reading the file and you're using VHDL'93, you can
close and re-open files. In VHDL'87, it's much harder to do so.

If the simulator is reading your stimulus file, check with your
documentation or the vendor.

Regards,

Paul

You need to have the file declaration inside a procedure. You may pass
the string into the procedure. Everytime the procedure is called, the
file is opened. All files declared in the procedure (i.e., in the
declaration section of the procedure) are closed when the procedure
terminates.
