No, the Intel® Stratix® 10 timing model in the Intel® Quartus® Prime Pro Edition software version 18.0 Update 1 and 18.1 has a small miscorrelation. This is corrected in the Intel Quartus Prime Pro Edition software version 18.1 Update 1.
These design scenarios may be affected:
- Designs that use source synchronous clocking
- Designs with transfers between the reference clock and the output clock for IOPLLs
- Designs with transfers between output clocks from different IOPLLs with different reference clocks
Almost all designs will see timing delays change but most transfers will be unaffected because of either Common Clock Pessimism Removal (CCPR) or the transfer being asynchronous.
All Intel Stratix 10 designs should be reanalyzed for timing in the Intel Quartus Prime Pro Edition software version 18.1 Update 1 or a patched version of 18.0 Update 1 or 18.1.

1. Download and run the script lut8_iobuf_qsh_v3.tcl to check if the compiled design is affected by this problem.
Command -> quartus_sh -t lut8_iobuf_qsh_v3.tcl -project <project name> -revision <revision name> -npaths 100 -debug 0 -verbose -check_lutmasks -vo_file simulation/modelsim/<revision name>.vo
Output -> lut8check.rpt, iobuf.rpt, paths.csv
iobuf.rpt and paths.csv report the paths that are affected by the timing model change
2. If there are no paths identified as impacted, no action is needed.
3. If there are paths identified as impacted and using the Intel Quartus Prime Pro Edition software version 18.1 or earlier, rerun timing analysis using the patched version of the Intel Quartus Prime Pro Edition software version 18.0 Update 1 or 18.1
