Problem Title:
M1 Map - Warning:baste:102 - Logic enclosed by Fmap symbol '..' has too many inputs
Problem Description:
Urgency: Standard
Maps gives the following WARNING:
WARNING:baste:102 - Logic enclosed by fmap symbol
`U1/a1/sign_col/signed/sm_3_/m4/sign2_1/fmap_1/b/u1'
(output signal=U1/n1k)
has too many inputs. Up to 4 inputs are allowed.
Solution 1:
Map checks the number of inputs for the FMAP symbols
before it performs logic trimming.
This means that a signal connected to GND or VCC or
a signal that will eventually get optimized away will
be counted as an extra connection on which Map will
report a warning.
This Warning can be safely ignored in this case since
the FMAP will be properly used after optimization.
