XNFPREP - What causes the "ERROR 1303, comma required" in Orcad designs?
説明
Keywords: Orcad, ERROR 1303, comma required
Urgency: Standard
General Description: 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"
ソリューション
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 "_").
