Record #2714
Product Family: Software
Product Line: FPGA Implementation
Product Part: map
Product Version: 1.3
Problem Title:
M1.3.7-pc: map FATAL_ERROR:basnc:basncsignal.c:262:1.61 - could not find a bel for a signal
on pin G2
Problem Description:
URGENCY: Standard
DESCRIPTION:
In M1.3.7 when running map you may get fatal error such as this:
FATAL_ERROR:basnc:basncsignal.c:262:1.61 - Could not find a
bel for a signal on
pin G2 of comp dly_s/CLB3. Its current programmed state is
: CLKX:CLK ECX:EC
G2MUX:G2I XQMUX:QX DX:H SR:C3 EC:C4 H:#LUT:H=F H2:F
G:#LUT:G=G2
F:#LUT:F=F3+F2 SRX:RESET FFX:#FF SETX:SR Process will
terminate. Please
call Xilinx support.
Reference #: 100429
Solution 1:
This problem has been observed in Exemplar designs when these
are written out with FMAPs and EQNs.
If you are using Exemplar, turning off EQNs and MAPs
when writing out XNF from Exemplar Leonardo 4.0.3 may
eliminate the problem, which is associated with mapping
constraints generated by Exemplar.
In general, the "Could not find a bel" error message is
relatively generic, and all occurrences of such errors should
be verified against the latest revision of the Map program.
If the error still appears when processing the design with
the latest version of the software, and the workarounds
documented in the solutions referencing this error
message does not eliminate the error, it should be reported
as a separate bug.
This problem will be fixed in the M1.4 release.
Solution 2:
If you are using Exemplar Leonardo Synthesizer, another workaround is to write out xnf output with g
ates instead of EQNs and NOT to include mapping (set xnf_write_lut_binding FALSE, set xnf_write_clb_
packing FALSE).
