thanks for your reply~

I seems understand what you said,

maybe I can change the above sentance like this:

always @(posedge clk)

Busyhold_clkB <= ~TaskDone_clkB & (TaskStart_clkB | Busyhold_clk);

signal A set after meeting high level B,and keep high indefinitly.then the signal C will used to reset A.
