Answers Database MAP v1.5is2, COREGEN, SDA FIR: x4kma : 339 - The (symname) symbol "xx/xx" has no signal connected to B1. This pin must be connected . . . Record #6134 Product Family: Software Product Line: Coregen Product Part: Coregen Problem Title: MAP v1.5is2, COREGEN, SDA FIR: x4kma : 339 - The (symname) symbol "xx/xx" has no signal connected to B1. This pin must be connected . . . Problem Description: Urgency : Standard General Description:    This error may occur when using a PDA FIR.    This is the error message returned by MAP: ERROR:x4kma:339 - The HIERCY4_03 symbol "U7/B176" (output signal=U7/N5940) has     no signal connected to B1. This pin must be connected based on carry moded     ADD-G-F1 Solution 1: This error message may appear because the SDA FIR Filter module had the 'Cascade' option selected when it was generated, but the module was not being cascaded with another SDA FIR module in the design. Ensure that you make the proper connections when cascading two or more SDA FIR filters when generating an SDA FIR with a Cascadeable Section (see the datasheet for the filter). If you are not going to cascade two or more SDA FIR filters together, do not activate the "Generate Cascadeable Section" checkbox. End of Record #6134 - Last Modified: 06/10/99 15:47
