I am using ISE 14.7, trying to generate the secureip library for Questasim. When I run compxlib with this command,
compxlib -s questa -l vhdl -p C:\Apps\questasim107b\nt64\ -w -lib unisim
It doesn't create the library and I get many errors in the compxlib.log file like this:
BEGIN_COMPILATION_MESSAGES(questasim:vhdl:unisim)
QuestaSim-64 vmap 10.7b Lib Mapping Utility 2018.06 Jun 8 2018
vmap unisim C:\apps\Xilinx\14.7\ISE_DS\ISE\vhdl\questasim\10.7b\nt64/unisim
Modifying modelsim.ini
** Warning: (vcom-159) Mode option -32 is not supported in this context and will be ignored.
QuestaSim-64 vcom 10.7b Compiler 2018.06 Jun 8 2018
** Error (suppressible): (vcom-12110) All optimizations are disabled because the -novopt option is in effect. This will cause your simulation to run very slowly. If you are using this switch to preserve visibility for Debug or PLI features, please see the User's Manual section on Preserving Object Visibility with vopt. -novopt option is now deprecated and will be removed in future releases.
Errors: 1, Warnings: 1
I get the same errors when I run "Compile HDL Simulation Libraries" from the Process menu.
What am I missing?
thanks,
John

As Hong pointed out, it's recommended that you run in Questasim 10.1b, which is compatbile with ISE 14.7.
Please refer to ISE Release Notes, pg9, Table 2-2.

The compilation script generated by compxlib has option -novopt in vcom/vlog commands. This option is deprecated in 10.7, and hence the error.
