Error : 'math_real' is not compiled in library ieee

library IEEE;  
use IEEE.std_logic_1164.all;  
use IEEE.std_logic_arith.all;  
use IEEE.math_real.all;

This is how I declared the libraries in my VHDL code. But the tool gives me an error saying:

Error : 'math_real' is not compiled in library ieee

I am using JasperGold from Cadence. In that, I am using FPV app.

Has it something to do with the tool? Or is something else wrong?

Solution

  • I found the solution to this question. I had to analyze it again in Jaspergold with switch option -lib and with name IEEE.

    analyze -vhdl93 -lib ieee \
  ${ROOT_PATH}/resources/IEEE/rtl/vhdl/math_real_p.vhd \
  ${ROOT_PATH}/resources/IEEE/rtl/vhdl/math_real_b.vhd

    Other packages were compiled into the IEEE library (e.g. std_logic_1164) and there was no need to compile them again.

    Since math_real is not synthesizable, JasperGold had ignored it at the first place.
