Hi,
It run into error when mapping my spartn6 based design, the error info as below,
ERRORlace:1023 - Unroutable Placement! A global clock component <userapp_inst/bufgce_inlp> configured as a selectable
mux is placed in site BUFGMUX_X2Y1. This configuration requires that the global clock site BUFGMUX_X2Y2 either be
empty or contain a global buffer or mux with the inputs IN0 and IN1 either not driven by a signal or driven by the
same signals as the original muxes IN1 and IN0 pins respectively in order to route up both of the inputs. In other
words the input signal for IN0 on one buffer must be the same as the input signal driving IN1 on the other buffer (or
one of them must not be driven) to place the two buffers in the paired sites. The site BUFGMUX_X2Y2 has the global
buffer <userapp_inst/app_pcie_inst/PIO_EP/regs_module_inst/mux_msgwrclk> placed there. This design is unroutable.
ERRORack:1654 - The timing-driven placement phase encountered an error.
Does anyone has any suggestion on this?
Thanks in advance,
Gauz
