General Description: This error may occur when using a PDA FIR; the error message returned by MAP is:
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.
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 data sheet 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.
