Problem Title:
M1.3/M1.4 CPLD: Fitter warning xr5049 - invalid 'BUFG' parameter


Problem Description:
Keywords: hitop, 5049, bufg, clk, oe, sr, buf, ibuf, ckbuf

Urgency: standard

General description:

Putting the property BUFG=CLK/OE/SR on any internal symbol or
net causes the fitter to issue warning xr5049. It ignores the
BUFG=CLK/OE/SR property on symbols other than IBUF/BUF/CKBUF,
or their output nets.


Solution 1:

Use the BUFG=CLK/OE/SR property on the IBUF/BUF driving the
internal symbols or nets.
