Can you change the GPIO data width?

#1

Hi,

Is it possible to change the data width of the GPIO interface?
I need to trace a signal that is larger then 32 bits, and that throws an error in QuestaSim.

Hi Eric,

There is a dependency issue with the data width usage in the VVC packages vs VVC entity. I think you have to increase the C_VVC_CMD_DATA_MAX_LENGTH from 32 to a preferred size in the transaction_pkg. In the VVC entity the GC_DATA_WIDTH, which you are trying to set to above 32, is constrained to C_VVC_CMD_DATA_MAX_LENGTH, thus increasing it in the transaction_pkg should work.

Hi Marius,

Yes this works.
