Introducing Performance Analysis

The Performance Analyzer provides an interactive graphical representation of where ModelSim is spending its time while running your design. This feature enables you to quickly determine what is impacting the design environment's simulation performance. Those familiar with the design and validation environment will be able to find first-level improvements in a matter of minutes.

For example, the Performance Analyzer might show some or all of the following

• A non-accelerated VITAL library cell is impacting simulation run time
• A process is consuming more time than necessary because of non-required items in its sensitivity list
• A testbench process is active even though it is not needed
• A random number process is consuming simulation resources when in a testbench that is running in non-random mode

With this information, you can make changes to the VHDL or Verilog source code that will speed up the simulation.
