Hi everybody,
I've launched simulation of more than 12 (personal) VHDL designs, with
GHDL, Xilinx's ISim from ISE Design Suite 2013.1 (full) and with
Xilinx's XSim from Vivado Design Suite 2015.1 (full).
My initial goal was to find how much slower GHDL was compared to these
commercial simulators.
Note: I compiled GHDL against gcc 4.9 with isl, cloog, lto. Not tested
without. My PC is 64 bits ArchLinux.
I got a very nice surprise: all simulations were at least 2 times
faster, sometimes 4 times faster, than ISim and XSim.
Thank you to you and others for the figures. Surprize for me too!
Tristan.
