Using BluePrint's Autoplace All feature to place the periphery generates assignments that might cause an internal error in quartus_syn - Using BluePrint's Autoplace All feature to place the periphery generates assignments that might cause an internal error in quartus_syn Description If you invoke BluePrint\'s Autoplace All feature to place the periphery for the following designs, BluePrint generates assignments that might cause an internal error in Spectra-Q ™ Synthesis ( quartus_syn ) when they are added to the Quartus ® Prime Settings File ( .qsf ): Designs that have the SignalTap ™ II Logic Analyzer Trigger in to pin feature or the Trigger out to pin feature, or both, enabled. Designs that contain the Arria ® 10 Transceiver Native PHY IP core with the tx_analog_reset or rx_analog_reset signal connected to the top-level inputs. Resolution If your designs satisfy the listed criteria, avoid using BluePrint\'s AutoPlace All feature. Alternatively, remove the assignments that cause the internal error in quartus_syn . These assignments have targets to hierarchy paths of the form auto_fab_0|debug.export.* . For example: set_location_assignment IOOBUF_X142_Y44_N18 -to auto_fab_0|debug.export.alt_sld_fab_0_splitter_receive_1[0]~output -tag "BluePrint Location Assignment" Custom Fields values: ['novalue'] Troubleshooting FB330964; True ['novalue'] ['FPGA Dev Tools Quartus® Prime Software Pro'] 15.1.1 15.1 ['Arria® 10 FPGAs and SoCs'] ['novalue'] ['novalue'] ['novalue']
