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

Modelsim 10+ has very good 2008 support.

How come Altera make us do with 6.6d then? Do they have a deal with Mentor to seed a 'teaser'?

Its always been like that. The altera version is only updated once every couple of years.

Perhaps an apology is on order: Quartus II 11.1 comes with ModelSim ASE 10.0c!

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,

Apparently the thing to do is to use the 'work' as the container for user packages also.

--library CC_Data_Types ;
--	use CC_Data_Types.CC_Data_Types.all ;
library work ;
	use work.CC_Data_Types.all ;

This keeps the ModelSim link happy, and Quartus is fine with it too. (I suppose I used the 'use library' in a non-standard way. I never understood this VHDL library idea anyway ..)
