Description

Keywords: basncsignal.c, 263, bel

Urgency: Standard

General Description:
MAP fails with the following 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

CINMUX:0 SRX:RESET SRY:RESET

解决方案

This error generally indicates that MAP generated a component (CLB in this case) whose internal configuration is not compatible with its 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.

The failure is taking place during optimization; it can be avoided by modifying optimization options (in this case, -os balanced), or by disabling optimization entirely:

For Workstations:
setenv XIL_MAP_NO_LOGOPT 1

For PCs:
set XIL_MAP_NO_LOGOPT=1
