ModelSim -> Error: xxxxx.vhd(n): Library yyyy not found

The error:

Library cc_data_types not found.

can probably be resolved by

vmap cc_data_types rtl_work

I suspect that in the regmux code you have

library cc_data_types;

use cc_data_types.cc_data_types.all;

or something like that.

Modelsim is expecting to find these data types in that library, whereas your script compiles them into 'work'.

Alternatively you can

vlib cc_data_types

vmap cc_data_types cc_data_types

vcom -93 -work cc_data_types {C:/qdesigns/c-cam/bb/vhdl_packages/CC_Data_Types.vhd}

Or something pretty close to that ...

Cheers,
