Hierarchical ECO

Abstract

This use case demonstrates how to automatically fix ECOs in several modules. 'fix_modules' command is run on all modified modules.

ECO script

# GofCall ECO script, run_hier_example.pl
use strict;  
undo_eco;  # Discard previous ECO operations
setup_eco("eco_hier_example");  # Setup ECO name
read_library("art.90nm.lib"); # Read in standard library
read_design("-ref", "reference.gv");  # Read in the Reference Netlist
read_design("-imp", "implementation.gv");  # Read in the implementation Netlist Which is under ECO
fix_modules('smod', 'top'); # Fix these two modules
set_top('top');   # Set the scope to parent of 'smod'
report_eco();  # ECO report
write_verilog("eco_verilog.v"); # Write out ECO result in Verilog
write_soce("eco_soce.tcl"); # Write out TCL script for SOC Encounter
