Problem Description: A case has been seen where Map fails with the error: FATAL_ERROR:basnc:basncsignal.c:263:1.67 - Could not find a bel for a signal on pin F2 of comp L24/Q_OUT0. Its current programmed state is : CLKX:CLK ECX:EC CLKY:CLK DY:G G3MUX:G3I G2MUX:COUT0 CARRY:DEC XQMUX:QX YQMUX:QY ECY:EC DX:F EC:C4 FCARRY:CARRY GCARRY:CARRY G:#LUT:G=(G3*G1)+(~(G4@G2)*~G1) F:#LUT:F=F3+(~F1*~F3) CINMUX:0 SRX:RESET SRY:RESET This error in general is an indication that map generated a component (CLB in this case) whose internal configuration is not compatible with it's external connectivity. In this case, the F2 pin is improperly connected due to an error during optimization. Other cases of this error code may be due to other causes. Solution 1: The failure is taking place during optimization and can be avoided by modifying optimization options (in this case -os balanced) or by disabling optimization entirely:     setenv XIL_MAP_NO_LOGOPT 1 (WS)     set XIL_MAP_NO_LOGOPT=1 (PC) End of Record #6562 - Last Modified: 05/19/99 09:18
