What might cause an error in the code below?

Code:

SUBDESIGN dec_counter

(

Clear, ent, clk : INPUT;

value[3..0] : OUTPUT;

rco : OUTPUT;

)

VARIABLE

count[3..0] : DFF;

BEGIN

count[].clk = clk;

value[] = count[];

IF (clear) THEN

count[].d = 0;

ELSIF (enc & ent & (count[].q != 9)) THEN

count[].d = count[].q + 1;

ELSIF (enc & ent & (count[].q == 9)) THEN

count[].d = 0;

ELSE

count[].d = count[].q;

END IF;

rco = ((count[].q == 9) & ent);

END;

	a.	The "rco" signal
	b.	The "enc" signal
	c.	The "clk" signal
	d.	The "ent" signal

Each FF has an asynchronous active-low clear signal. The asynchronous active-low clear signal clears the FF and uses this signal to set the initial output of the FF to zero. (Active-low clear: clear when clear signal is low (0)). Implement negative edge-triggered T FF using Verilog code. At this time, The interface is as follows. Module t_ff (input t, input clk, input clearb, output q); How the waveform of q changes when the value of input t changes sequentially to...
