LPS Synthesis BuildGates 5

[Christoph Piotrowski]

Hi,
im testing the LPS flow of BuildGates5 (s007) and my flow for tcf-file
based power optimized synthesis looks like the following:

- read design files
- do_build_generic -sleep_mode
- do_optimize -power -stop_after mapping
- do_optimize -power -stop_for_power_simulation
- write netlist
- gate-sim: create tcf-file
- read netlist and tcf file
- 1. report power (*)
- do_optimize -power (**)
- 2. report power (*)

During this flow, sleep mode logic and clock gating logic seems to be
added. but I don't get any power difference comparing the two
report_power commands (*). Also the do_optimize -power (**) does not
show any power-decrease.
Does anybody uses the LPS flow and has an idea, what the reason for
equal power reports could be?
