(多选题, 2分)时钟上升沿检测语句可以是？ A: CLK'EVENT AND CLK='1' B: CLK'EVENT AND CLK='0' AND CLK'LAST_VALUE='1' C: CLK'LAST_VALUE='1' AND CLK='0' D: RISING_EDGE(CLK) E: FALLING_EDGE(CLK) F: CLK'EVENT AND CLK='1' AND CLK'LAST_VALUE='0' G: CLK'LAST_VALUE='0' AND CLK='1'

时钟信号CLK在进程中为敏感信号,可用于检测CLK上升沿的语句有 A: IF CLK'EVENT AND CLK=‘1’ B: IF CLK'EVENT AND CLK=‘0’ C: IF CLK=‘1’AND CLK'LAST_VALUE =‘0’ D: IF rising_edge(CLK) E: IF CLK=‘1’ F: wait until CLK=‘1’

CLK'EVENT AND CLK='1'表示CLK的 ( )

在所列对时钟上升沿检测的VHDL描述中，错误的是（ ）。 A: if clk’event and clk = ‘1’ then B: if falling_edge(clk) then C: if clk’ not stable and clk = ‘1’ then D: if clk’event and clk’last value=‘1’ then

时钟信号CLK在进程中为显式或隐式敏感信号，下面语句中不可用于检测CLK上升沿的是 。 A: IF CLK'EVENT AND CLK=‘1’ B: IF CLK'EVENT AND CLK=‘0’ C: IF CLK=‘1’AND CLK'LAST_VALUE =‘0’ D: IFCLK=‘1’

在Verilog语言中，下列对时钟上升沿检测描述中正确的是________ A: posedge clk B: negedge clk C: if clk’event and clk = ‘0’ then D: if clk’stable and not clk = ‘1’ then
