How to change a library refence in modelsim?

Hi Johi,

"hi Johi,

Can you please check the each & every port & ports type of the component instance 'squarer' & corresponding entity?

Especially sclr port."

It was my previous post.

The issue is squaring operation cannot be used together with synchronous clear signal for LPM_MULT.

It should not be on port list.

Refer below code from FloatLn.vhd file & try to simulate, here port "sclr" is commented in COMPONENT & remove it from Entity as well if you can.

 COMPONENT  altsquare
	 GENERIC 
	 (
		DATA_WIDTH	:	NATURAL;
		PIPELINE	:	NATURAL;
		REPRESENTATION	:	STRING := "UNSIGNED";
		RESULT_ALIGNMENT	:	STRING := "LSB";
		RESULT_WIDTH	:	NATURAL;
		lpm_type	:	STRING := "altsquare"
	 );
	 PORT
	 ( 
		aclr	:	IN STD_LOGIC := '0';
		clock	:	IN STD_LOGIC := '1';
		data	:	IN STD_LOGIC_VECTOR(DATA_WIDTH-1 DOWNTO 0);
		ena	:	IN STD_LOGIC := '1';
		result	:	OUT STD_LOGIC_VECTOR(RESULT_WIDTH-1 DOWNTO 0)
		--sclr	:	IN STD_LOGIC := '0'
	 ); 
	 END COMPONENT;
 
 
 
squarer :  altsquare
	  GENERIC MAP (
		DATA_WIDTH => 13,
		PIPELINE => 1,
		REPRESENTATION => "UNSIGNED",
		RESULT_ALIGNMENT => "MSB",
		RESULT_WIDTH => 14
	  )
	  PORT MAP ( 
		aclr => aclr,
		clock => clock,
		data => squarerIn,
		ena => clk_en,
		result => wire_squarer_result
		  );

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

Best Regards
