Virtex-4 RocketIO - Why do I receive a Fatal Error when simulating the MGT in ModelSim 6.1?

Description

Why do I receive a Fatal Error when simulating the MGT in ModelSim 6.1?

Solution

The problem results because of a change made in an optimization function in the simulator. MTI is aware of this issue and is working on a solution.

In the meantime, there are two possible ways to work around this issue:

- In ModelSim 6.1, use the "-nopartialatomic" flag to the vsim command.

For example:

vsim -nopartialatomic -L unisim work.SAMPLE_TB

- Or, use ModelSim 6.0x.
