Your script -merge options vary according to family as shown below:

  • The -merge_timing, -merge_physical, and -merge_all arguments are available for IGLOO, Fusion, ProASIC3, ProASIC PLUS, ProASIC, and Axcelerator families.
  • For source SDC (no PDC/GCF) in eX and SX-A:

import_source -merge_timing yes/no ...

import_source -merge yes/no ... import_source -merge_all yes/no ...

The eX and SX-A families do not support merging of physical constraints. For these families, in import_source, the

-merge_all and -merge options are mapped just to -merge_timing.

  • For constraints in ProASIC PLUS:

import_source -merge_physical yes/no ... import_source -merge_all yes/no ... import_source -merge yes/no ...

ProASIC PLUS and ProASIC support GCF, but the -merge option in the import_source only affects GCF in terms of the physical constraints.

  • ProASIC does not support PreCompile import of the SDC files. The -merge_timing option has no effect on this import_source for ProASIC. The -merge_all and -merge options map to -merge_physical for ProASIC in import_source.

  • For IGLOO, Fusion, ProASIC3, ProASIC PLUS, and Axcelerator:

    import_source -merge_physical yes/no -merge_timing yes/no ... import_source -merge_all yes/no ...

    import_source -merge yes/no ...

The -merge_all and -merge options map to both -merge_physical and -merge_timing options for these families.
