Problem Title:
2.1i 9500/XL Hitop: Designs that fit in 1.5x do not fit in 2.1i
Problem Description:
Urgency : Standard
General Description:
A 9500/XL design that fit in 1.5x no longer fits in 2.1i.
Solution 1:
Most cases of this arise because the default settings for the fitter have changed from
1.5x to 2.1i. Check the bottom of the fitter report to verify that the fitter options are
what they were in 1.5x.
Solution 2:
A fitter bug that caused the fitting to fail even with the same options was fixed in
the latest 2.1i Service Pack available at:
