The syntax is:% property_name property_valueThis method is used by the models to map the pins from the BUS symbols to the model.The pin map parser searches for the property_name in the design database and thencompares the property_value. If the property is not present, or if the actual value of theproperty does not match the property_value exactly, everything in the file until the nextpercent sign (%) is ignored.The following example shows the pin_map file that provides mapping from the pin tothe bus symbols for the Logic Devices LSH32 32-bit barrel shifter.## Bus Package for the LSH32#% PKG BUSIN I = I31 I30 I29 I28 I27 I26 I25 I24 I23 I22 I21 I20 I19 I18I17 I16 I15 I14 I13 I12 I11 I10 I9 I8 I7 I6 I5 I4 I3 I2 I1 ;OUT Y = Y15 Y14 Y13 Y12 Y11 Y10 Y9 Y8 Y7 Y6 Y5 Y4 Y3 Y2 Y1 Y0 ;IN SI = SI4 SI3 SI2 SI1 SI0 ;OUT SO = SO4 SO3 SO2 SO1 SO0October 6, 2003 Synopsys, Inc. 149
