-64 : Forces execution explicitly within the 64-bit engine workspace.
ModelSim 10.7 brings a mature, stable, and feature-rich environment to the design flow. Mentor Graphics ModelSim SE-64 10.7
In addition to memory capacity, the 64-bit kernel handles data structures more efficiently, resulting in faster simulation throughput. 4. Debugging and Verification Efficiency -64 : Forces execution explicitly within the 64-bit
