how to write a conditional assignment over generic or consta

[sm.soimu@gmail.com]

Hello,

I would like to write in VHDL an equivalent code for:

parameter INSTANCE = 1;
parameter DATA_WIDTH = (INSTANCE == 1) ? 8 : 16;

The equivalent for parameter statement should be generic or constant,
but I see no way to write the equivalent VHDL code for the above
VERILOG code.

Can anyone suggest any way to write it?

Thank you in advance!

Regards,
Sorin SOIMU

Write your own function.
