The most straightforward way to check if a vector contains any value, is to compare it with a hard-coded bit literal. The problem with this approach is that if we change the length of the vector, we have to change the length of the hard-coded literal as well.

0. Your variable is a std_logic_vector and you compare it to an integer. You have to cast the std_logic_vector like this: if (to_integer (signed (row)) = 1) or if (to_integer (unsigned (row)) = 1) The IF-THEN-ELSE is a VHDL statement that allows implementing a choice between different options. When the number of options greater than two we can use the VHDL “ELSIF” clause. In case of multiple options, VHDL provides a more powerful statement both in the concurrent and sequential version: hie all im trying to write an If STATEMENT in VHDL but i get an error i dont understand.Please help: if( c(2 DOWNTO 0) = "0 1 0") I'm using VHDL 2008, so I'll do it with two separate if generate statements – po.pe Nov 14 '19 at 16:27 @Eugene Sh it was added in vhdl2008.

This VHDL project presents a simple VHDL code for a comparator which is designed and implemented in Verilog before. Full VHDL code together with test bench for the comparator is provided. The design for the comparator based on the truth table and K-map are already presented here. There are two 2-bit inputs A and B to be compared.

Know the principles of ISO9000.

VHDL-93 defines an unaffected keyword, which indicates a condition when a signal is not given a new assignment: label: signal = expression_1 when condition_1 else expression_2 when condition_2 else unaffected ; They can be used inside an if statement, a when statement, and an until statement. One important note is that VHDL is a strongly typed language. This means that when comparing two signals for their relationship, the signals that are being compared need to be of the same type.

History of VHDL. VHDL was developed by the Department of Defence (DOD) in 1980. 1980: The Department of Defence wanted to make circuit design self-documenting. 1983: The development of VHDL began with a joint effort by IBM, Inter-metrics, and Texas Instruments. 1985 (VHDL Version 7.2): The final version of the language under the government contract was released.
