Problem Title:
M1.4 Map - FATAL_ERROR:x4kma:x4kmagrclapse.c:1001:1.90.12.8 - No

Problem Description:
Keywords: map, -k, function, 5 input, generate

Urgency : standard

General description:
When -k option ( Generate 5-input functions) is used in map
with core patch #14, map is terminated with the following
error:

FATAL_ERROR:x4kma:x4kmagrclapse.c:1001:1.90.12.8 -
No route-thru available in
pack_lutflop() to swap with H input pin 8:
cpu_reg_blk/U1942/O/cpu_reg_blk/n1021<16>. Process will
terminate.  Please call Xilinx support.



Solution 1:

The workaround is to not use the -k option.

In GUI, check to see that the option,"Generate 5-input Functions" is not checked
.
