orcad 9.1 express

Feb 20, 2006 3 Replies

Hello: I'm newbie to Orcad 9.1 express, I'd like to synthesize a gal22v10 with a simple vhdl file just to test, I wrote the following file:



library ieee;



use ieee.std_logic_1164.all; use ieee.STD_LOGIC_UNSIGNED.all; use WORK.mylib1.all;



entity cmp_bdt is port( CLOCK : in std_logic; RESET : in std_logic; CK1 : out std_logic; CK2 : out std_logic; CK3 : out std_logic); end cmp_bdt;



architecture arch_behavioral of cmp_bdt is -- Component declarations -- Signal declarations signal cpt : std_logic_vector(2 downto 0); begin



GEN_CPT: process(CLOCK,RESET) begin if (CLOCK'event and CLOCK='1') then if (RESET='1') then CPT


Well "doh"! Orcad is a reasonably good analog schematic capture tool, but it is not a front end to VHDL or Verilog; they have their own front ends.

Actually, no. Orcad Express was a VHDL tool, that used Capture as its front end, and not too bad a one at that. It was lost after the purchase by Cadence.

If you find it so fine for you. I had always accepted that VHDL was a move to behavioral modeling (ignited by Conway-Meade) per the US military VHSIC program; which was a move away transistor level modeling. Of course a good generalized schematic capture tool might very well do the job. Don't get me wrong, i liked Orcad back in the 1980's when i had a running version.
