Why do I see errors when compiling the Video Sync Generator in Quartus II 13.0 and 13.0sp1.

Description

Due to a problem in the Quartus® II software version 13.0 and 13.0sp1,  the Video Sync Generator component does not declare HDL parameters for Qsys systems generated in Verilog.

Resolution

To workaround this issue manually remove the 2 lines below in the altera_avalon_video_sync_generator_hw.tcl file, refresh the Qsys systemand regenerate the Qsys system.

package require -exact sopc 9.1

set_module_property ANALYZE_HDL "false"

This problem is fixed beginning with the Quartus II software version 13.1.
