LogiCORE PCI - During simulation, pull-ups must be placed on all signals designated s/t/s in the specification

Description

General Description:

During simulation, pull-ups must be placed on all signals that are designated s/t/s in the specification.

Solution

All signals in the specification that are designated as s/t/s (sustained 3-state) must have a pull-up simulating the bus pull-up, or the simulation will fail.

The signals in question are:

FRAME#, IRDY#, TRDY#, STOP#, LOCK#, DEVSEL#, PERR#, CLKRUN#

REQ64#, ACK64#

NOTE: The Xilinx UniSim library component "PULLUP" should be used for functional simulation. Please refer to the answers database for examples on how to instantiate the PULLUP component.
