-- Id: R.2 function RESIZE (ARG: UNSIGNED; NEW_SIZE: NATURAL) return UNSIGNED; -- Result subtype: UNSIGNED(NEW_SIZE-1 downto 0) -- Result: Resizes the SIGNED vector ARG to the specified size. -- To create a larger vector, the new [leftmost] bit positions -- are filled with '0'.

Bug. DrPi October 5, 2017, 9:05am #1. Before submitting a bug I’d like to check my assumptions are correct. I have the following in a design : VHDL: (vcom-1136: std_logic_vector undefined) syntax,vhdl. The use of IEEE.std_logic_1164.all is also required before the entity, like: library IEEE; use IEEE.std_logic_1164.all; entity lab2 is The first IEEE.std_logic_1164.all only applies to the package, and package body of the same package, but not to any other design objects like an entity or package, even if these happens to The most convenient and recommended method for resizing vector elements in VHDL is the 'resize' function. This function takes a vector and resizes according to the requested length.

RESIZE (v,n) Note: when increasing the size of a signed vector the leftmost bits are filled with the sign bit, while truncation retains the sign bit along with the (n-1) rightmost bits. For an unsigned vector, a size increase fills the leftmost bits with zero, while truncation retains n rightmost bits. Description. The Resize-VHD cmdlet changes the maximum physical size of a virtual hard disk.

In VHDL, there are two types of functions, pure and impure functions. widely used scalar VHDL values. The standardization activity started during the development of IEEE Std 1076-1993, IEEE Standard VHDL Language Reference Manual, to address a number of issues in the synthesis area that could not be ade-quately addressed within the scope of the main 1076 project. VHDL • Parallel programming language(!) for hardware – Allows sequential code portions also • Modular – Interface specification is separated from the functional specification • Allows many solutions to a problem • The coding style matters! – Different solutions will be slower and/or larger than others – Save money!

Could someone enlighten me. use ieee.numeric_std.all; constant JUNK : std_logic_vector (19 downto 0) := "00000000000000001100"; constant JUNK2 : unsigned (15 downto 0) := resize (JUNK, 16); I've tried typecasting JUNK but to no avail. resize function. RESIZE(v,n) Note: when increasing the size of a signed vector the leftmost bits are filled with the sign bit, while truncation retains the sign bit along with the (n-1) rightmost bits.

The Resize-VHD cmdlet changes the maximum physical size of a virtual hard disk. It can expand both VHD and VHDX files but can shrink only VHDX files.
