Simulation of ALTMEMPHY IP with Cyclone IV Devices Fails

Description

This problem affects all ALTMEMPHY-based external memory interfaces targeting Cyclone IV devices.

Simulation of an ALTMEMPHY-based external memory interface fails with the following error message:

can't read "lib_list(cycloneiii_ver)": no such element in array

Cyclone IV simulations require Cyclone III libraries, because many atoms and modules from the earlier family are reused. The problem is that Cyclone III has reached end-of-life, and its libraries have been removed from the Quartus II software version 14.0. Consequently, simulations of ALTMEMPHY-based IP on Cyclone IV devices in the Quatus II software version 14.0 or later, will fail.

Workaround/Fix

The workaround for this issue is to use a version of the Quartus II software earlier than 14.0.

This issue will not be fixed.
