Problem Title:
BitGen M1.5: Startup Clock can be specified by options or read from design
Problem Description:
Urgency: HOT
General Description: There has been a change in behavior for
BITGEN beginning with the M1.5 release.
Solution 1:
With previous versions of M1, the startup clock could only be
specified by command line options '-g StartupClk:CCLK' to
specify the configuration clock or '-g StartupClk:UCLK' to
specify the use of a user supplied clock.
However, with the 1.5 release BITGEN analyzes the design to
see if any nets are connected to the CLK pin of the STARTUP
block and if so will automatically default to User Clock for
the startup cycle.
