Matrix Package in VHDL

[Altera_Forum]

Hello, I have found that there is matrix package provided by Altera which includes several functions that we can perform on matrices. Anyone who has already used this package?? Since I am creating matrices in fixed_package format and this package also supports the functions for matrices created in fixed format, i just want to confirm that whether should i use it or not??

Which package is this? 

I have never seen such a package created by altera - link?

This package is for modelling only. You cannot synthesise with this package.

This package uses real types.  

You could use the integer matrices, but the real matrices are not suitable (real types have no meaning to a synthesisor)  You need to define your own types , in your own package, with the fixed point package.

It gave me no error... I have also attached the snapshot of compilation page. I think I should use it and see whether I can achieve my result or not. What you suggest?  entity matrix_multiply is port ( clock : in std_logic ); end matrix_multiply;  architecture matrix_function of matrix_multiply is  signal i_es_alpha : sfixed(15 downto -12);  begin   multiply: process (clock)    variable matrix_a : sfixed_matrix (0 to 1, 0 to 1);    variable matrix_b : sfixed_matrix (0 to 1, 0 to 1);    variable matrix_c : sfixed_matrix (0 to 1, 0 to 1);  variable resizing : sfixed (15 downto -12);  begin  if rising_edge(clock) then  matrix_a := ((to_sfixed(1,15,-12),to_sfixed(2,15,-12)),(to_sfixed(5,15,-12),to_sfixed(8,15,-12)));  matrix_b := ((to_sfixed(5,15,-12),to_sfixed(2,15,-12)),(to_sfixed(7,15,-12),to_sfixed(8,15,-12)));    matrix_c := matrix_a*matrix_b;  end if;  i_es_alpha <= matrix_c(1,1);  end process multiply;   end architecture matrix_function;https://www.alteraforum.com/forum/attachment.php?attachmentid=10580

input : clk 

output: nothing  that makes compilation very easy and empty.  BTW this forum website is badly broken , it took me 4 times to login in order to login...not very encouraging.

Hi,Do you have seen this prob: Could not find the package (mgc_axi4_pkg)

[Altera_Forum]

mgc_axi4_pkg will be a custom package you need to compile and load with your design.
