4.2i ECS - "ERROR:"HDLParsers:162 - xxx.vhf Line xxx. Read symbol '(', expecting ',' or ':'."

Description

Keywords: ISE, ECS, XST, ERROR, HDLParsers, 162, vhf, schematic

Urgency: Standard

General Description:
When I synthesize a schematic in ISE with the XSTVHDL design flow, the following error is reported:

"ERROR:HDLParsers:162 - xxx.vhf Line xxx. Read symbol '(', expecting ',' or ':'."

Solution

When naming I/O markers (especially when doing so from a bus), you cannot use the following characters: (), {}, or []. If these brackets are used, illegal VHDL code will be created within the .vhf file in the port declaration.

To work around this restriction, add a buffer between the bus tap net and the I/O marker; give the I/O marker a name that does not contain (), {}, or [].
