1   when PEX extraction(calibreview), it has the following warnings:

unable to find a map for port "R_" on the template for cell "SH1"
"R_" will NOT be ported for this cell

unable to find a map for port "S_" on the template for cell "SH1"
"S_" will NOT be ported for this cell

what is the meaning? and not every port can't be ported, for my cell, only three of fifteen can't be ported, the other is correct.

besides, 'template file canot be read' is another warning.


2   sometimes for some cell, the following warnings:

pin not connected for cell AMP_1 (30) local nn=18 net num=10 pin_layer=593 seed_layer=18;


how to solve the two problems, if i don't use template file(.stl) for the first one, then will it be ok? how to do?

pls help me. thanks.

i also want to say, my lvs check is ok. no error exists. thanks in advance.
