4.1i UNISIMS, SIMPRIMS - Simulation of the DCM breaks when it moves from version 3.3i to 4.1i (VHDL)


Keywords: UniSim, SimPrim, libraries, DCM, instantiation, generic, startup_wait, simulation

Urgency: Standard

General Description:
Simulation of the DCM breaks when it moves from software version 3.3i to 4.1i. Why?


In ISE 4.1i, the FACTORY_JF, STARTUP_WAIT, and DSS_MODE generics were erroneously removed. Because of this, if the design is mapping these generics, an error will result when it tries to instantiate the DCM.

This problem will be fixed in an upcoming service pack. In the meantime, the work-around is to comment out the lines that map these generics in the design.
