F1 XABEL - Error:hi301 - cannot fit the design into any of the specified devices
Description
Keywords: foundation, xabel, hi301, fit Urgency: Standard
General Description:
A 9500 ABEL design originally compiled in Foundation 6.x fit in a given device without any problems when using XACT-CPLD 6.0.1.
Compiling the same design in Foundation F1.x and implementing with M1 software, however, does not fit into the same device successfully.
The error returned in the fe.log report is:
hi302 - Insufficient number of macro cells: needs at least 133 but only 108 left after allocating other resources. Device XC95108-PC84 was disqualified.
ERROR:hi301 - Cannot fit the design into any of the specified devices. You may want to decrease the pterm limit for a denser fit, or split the design into sub-designs, or try a larger device.
Solution
1
A workaround is to have XABEL write out a Plusasm (.PLD) file instead of an Edif (.EDN) file. This PLD file will be read by the Design Manager rather than the EDN file for implementation. The detailed procedure is outlined in (Xilinx Solution 2776)
