It is possible to force the Hardware Simulator to load a built-in version of chip Xxx. This can be done by: Select one: a. making sure the Xxx. hdl file is not loctaed in the current directory. b. leaving the chip body in the Xxx. hdl file empty. c. stating in the chip header that this is a built-in chip. d. once the chip was implemented by the user, this is not possible.

C. Stating in the chip header that this is a built-in chip

Explanation:

The header of an HDL program is as follow:

CHIP chip name

{

IN input pin name

//statements

}

The simulator is using the following logic:

If Xxl.hdl exists

then load it into the simulator

else if Xxl.hdl exists in the built-in chip

then load it into the simulator and chip header

else

display "error message"

c. stating in the chip header that this is a built-in chip.

Explanation:

The header of an HDL program is as follows;

CHIP chip name

{

IN input pin name

// statements

}

Syntax:

The stimulator is using the following logic

If Xxx.hdl exists

then load it into the stimulator

else if Xxx.hdl exists in the built-in chips

then load it into the stimulator and the chip header

else

display "error message"
