Just wondering if it is possible to create variable and dereference it by using $var.

Need to define a variable holding absolute path. Desired to be able to use it as $var/../

Thanks,
:roll:
 

yes - modelsim scripts are just tcl

set var /some_path/

vcom $var/my_vhdl_file.vhd
 

As TrickyDicky says. Modelsim transcript just runs tcl commands.

The thing about tcl is "Everything is a string"

There are some key substitution characters which are $ and \.

When using quotations "this\n is \\ a test of var $var" The substitution takes places
Whereas when using curly brackets {} what is contained within is passed entirely as is

type in the following into the modelsim transcript

Code TCL - [expand]
1
2
set var_a "tes\ts"
set var_b {tes\ts}
