I received a Sigasi Editor update email which had the following statement:

"Xilinx no longer ships ModelSim with ISE but now ships its own HDL simulator
that enables functional and timing simulations for VHDL, Verilog and mixed
VHDL/Verilog designs: ISim."

Is this correct?

Although ISIM is not bad it is still a long way from being Modelsim (even though
the MXE(starter) edition is fairly limited),

Interesting. Altera is taking exactly the opposite approach. The first
time I started Quartus II v9.1 SP1 I got a message that said their
native simulator would not be included "in future versions" of the
software. Talking with my FAE, he stated that starting with version
10.0 only ModelSim-Altera would be included.

Has anyone here tried the Xilinx simulator? How is it's performance
relative to commercial simulators?

Modelsim Starter is severely crippled so it wouldn't be a particularly
hard task to produce a simulator that out performs it. Both Xilinx and
Altera of produced synthesis tools that are competitive with Synplify, it
would be interesting if Xilinx had ambitions to produce a simulator that
was as fast as Questa, or better yet as fast as NCsim.

Xilinx still provides ModelSim XE (Xilinx Edition),

I dunno, but I was still able to download the latest Modelsim MXE from
Xilinx today, version 6.4b from 04/06/2009. But considering it's
fairly old, maybe it's true. I'm sure Xilinx is very happy if they can
stop stuffing Mentor's coffers and ship their own ISIM instead.
