XNFPREP - What causes the "ERROR 1303, comma required" in Orcad designs?
Keywords: Orcad, ERROR 1303, comma required
Orcad allows a sheet symbol to be given a name that contains spaces. If this
is done in a Xilinx design, XNFPREP will issue the following error:
XNFPREP: ERROR 1303: The following problem(s) were found in
the <design>.xff file; the file could not be processed successfully.
A comma is required on line <line#> of file <design>.xff:
"HIERG, 1, <filename>, <sheet name>, <filename>.xnf, 0"
Because of the space in the sheet name, the hierarchical prefix contains spaces.
This is not a legal Xilinx name.
To avoid this error, change all sheet names to legal Xilinx names (for example, replace
spaces with "_").
