Error: Text Design File syntax error: Text Design File contains a symbolic name, but must contain '(', Error: Node instance auto_generated instantiates undefined entity sld_ela_trigger_qdm

Description

The following errors may occur in the Quartus^® II software version 4.0 when you have white space characters in a SignalTap^® instance name:

• Error: Text Design File syntax error: Text Design File contains a symbolic name, but must contain '('
• Error: Text Design File syntax error: Text Design File contains a symbolic name, but must contain ';'
• Error: Node instance auto_generated instantiates undefined entity sld_ela_trigger_qdm

The workaround for these errors is to change each white space in the SignalTap instance name to an underscore character (_).

This error has been fixed in the Quartus II software version 4.1.
