design compile synthesis user guide

This directory contains the source codes, the db files, the script
files and the log file for this ECO tutorial.  They are located in
various sub-directory as below,

1. Source codes in both VHDL and Verilog are found in the ./src directory.
   The source codes of the original design are uwave.v or uwave.vhd.  The
   source codes of the new design with ECO changes are nu_uwave.v or 
   nu_uwave.vhd.

2. The db files (compiled source codes) are found in the ./db directory.
   The old_hdl.db and the old_netlist.db are the hdl and the gate level 
   netlist of the original design.  The old_netlist.db and new_netlist.db
   are the hdl and the gate level netlist of the new design.  The eco_*.db
   are the eco netlist generated at various stage of the ECO flow.

3. The dc_shell script to create the above db files is ./scripts/create_db.scr.

4. The dc_shell script to exercise this tutorial is ./scripts/eco.script.
