AR# 2193: M1 Map - Warning:baste:102 - Logic enclosed by Fmap symbol '..' has too many inputs
M1 Map - Warning:baste:102 - Logic enclosed by Fmap symbol '..' has too many inputs
Keywords: Map, warning, coregen, core generator, multiplier 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.
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.
