137 - LatticeECP2/M: Why doesn’t the testbench, included in the Basic Demo for the LatticeECP2M PCIe DevKit, simulate properly?
Description:
The most likely scenario is the customer using an older version of the software. The LatticeECP2M Basic Demo testbench in the PCIe DevKit requires ispLEVER version 7.2 Service Pack 1 or later. Simulating the testbench with an earlier version of the software causes the endpoint to not finish link training so the Transaction Layer Packet (TLP) traffics are not sent across the link.
