I have two netlists, a revised and a golden, both containing a mesh/tree hybrid comprised entirely of inverters. There are multi-driven nets and bidirectional ports galore, but the input to the tree is a pin/net called "clk", and the output is a net called "GCK".
When I load these two netlists into Conformal, I get this message when attempting to run a compare:
LEC> compare// Command: compare// Nothing to compare. 'Add compared points' first.
When attempting to add a compare point, I get:
LEC> add compared points clk -golden// Command: add compared points clk -goldenThese mapped points are not compared: (G) + 1 PI /clk (R) + 1 PI /clkLEC> add compared points clk -revised// Command: add compared points clk -revised// Warning: 'clk' in Revised is not a mapped point// Warning: No compared point is added
LEC> add compared points clk -golden// Command: add compared points clk -goldenThese mapped points are not compared: (G) + 1 PI /clk (R) + 1 PI /clk
LEC> add compared points clk -revised// Command: add compared points clk -revised// Warning: 'clk' in Revised is not a mapped point// Warning: No compared point is added
A very basic example dofile is as follows. You may not need some of the options but this is a good start for much designs.
read library -verilog -replace -both <lib_files>
read design -verilog -golden <design_files>
read design -verilog -revised <design_netlist>
report design data
report black box -detailadd pin constraint 0 scan_en -golden/revised
add ignore output scan_out -golden/revised
set flatten model -seq_constant
set flatten model -gated_clock
set analyze option -auto
set parallel option -threads 4
set system mode lecadd compared point -all
It seems like your main problem is with "add compared points". You are only trying to compare the input clk in your design. This isn't adding the needed compare points to your design.
There is this new Web Interface feature (11.1) that for me has a lot of good information. You may try that or the LEC Jumpstart which is a good starting point.
