Error: Parameter user_offset_enable is not supported for WYSIWYG primitive "sdl" - Error: Parameter user_offset_enable is not supported for WYSIWYG primitive "sdl" Description You may see this error in the Quartus® II software version 9.0 SP2 and earlier for designs targeting Stratix® IV devices when using the ALTTEMP_SENSE megafunction. This problem only affects ALTTEMP_SENSE megafunction variation files generated in VHDL. To work around this problem, perform either of the following steps: Regenerate the ALTTEMP_SENSE megafunction variation file in Verilog HDL, which is unaffected by this problem Comment out line 73 from the ALTTEMP_SENSE megafunction VHDL variation file ( .vhd ) user_offset_enable : STRING := "off"; This problem is fixed beginning with the Quartus II software version 10.0. Custom Fields values: ['novalue'] Troubleshooting novalue False ['novalue'] ['novalue'] novalue novalue ['Stratix® IV E FPGA', 'Stratix® IV GT FPGA', 'Stratix® IV GX FPGA'] ['novalue'] ['novalue'] ['novalue']
