Subject: What's The Customer Dirt On ModelSim's Verilog/VHDL Co-Simulation?

Hi John,

We're thinking about using Modeltech's ModelSim to simulate a Verilog gate
level design in a VHDL-Testbench.  (We want to reuse the VHDL testbench we
designed together with the Verilog RTL code of the design.)  I'm interested
in any user experiences with ModelSim's Verilog engine & their VHDL/Verilog
co-simulation.   How about their:

        - Simulation time ( especially for designs about 100k gates)?
        - Compile time ( especially for designs about 100k gates)?
        - Backannotation (again, for 100k gates)?

If someone has experiences compared to Verilog-XL or Synopsys's VCS or
Viewlogic's Fusion, it would be great.  Many thanks for moderating the
ESNUG, John.
