Hi, there:
I am using some 14 global clock buffers in the design, I instantiated all of them as BUFGMUX...for example...
In simulation, it showed some gray time on clk_12m at the two transitions of sel...how may I do correct this?
BUFGMUX CLK_BUF2( .O( clk_12m ), .I0( clk_12m_o ), .I1( clk_12m_o ), .S( sel ) ); //1 BUFGMUX CLK_BUF2( .O( clk_12m ), .I0( clk_12m_o ), .I1( ), .S( sel ) ); //2 BUFGMUX CLK_BUF2( .O( clk_12m ), I( clk_12m_o ) );
initial begin sel
