ID:18499 FPLL < <name> > are too close to ATX PLL < <name> >. FPLL with VCO frequencies within 50 MHz of adjacent ATX PLL must be separated by one FPLL. Modify the FPLL location constraints in the Assignment Editor to make FPLLs at least one ATX PLL apart.

CAUSE: Can't place FPLL with VCO frequencies within 50 MHz of adjacent ATX PLL at current location.Two FPLL's distance is too close to the ATX PLL to meet coupling requirement.

ACTION: Modify the location constraint of FPLL in the Assignment Editor.
