mod-16カウンターを作成し、出力結果はINTEGERです（見たすべての例ではINTEGERを使用しました）。. hex-to-7-segment-displayデコーダーを作成しましたが、その入力はSTD_LOGIC_VECTORです（真理値表を簡単にマップできたため、そのように書きました）。. カウンターの出力をデコーダーの入力に接続したいのですが、QuartusIIでコンパイル The basic VHDL logic operations are defined on this type: and, nand, or, nor, xor, xnor. These must be given two arrays of the same size; they do the operation on ecah position and return another array.

CONV_STD_LOGIC_VECTOR--Converts a parameter of type INTEGER, UNSIGNED, SIGNED, or STD_LOGIC to a STD_LOGIC_VECTOR value with SIZE bits. Verilog的数据类型和VHDL不一样，integer可以直接assign给array。----- Now that I've implemented the function, added it to my top level code I get the following error: ERROR:HDLCompiler:1690 - Line 982: This construct is only supported in VHDL 1076-2008 Checking the design properties and the CHDL Source Analysis Standard is set VHDL Type Conversion. Posted by Shannon Hilbert in Verilog / VHDL on 2-10-13. Any given VHDL FPGA design may have multiple VHDL types being used. The most common VHDL types used in synthesizable VHDL code are std_logic, std_logic_vector, signed, unsigned, and integer.

タイプ変換は、VHDL コードの記述中に実行される通常の処理ですが、場合によっては扱いにくいことがあります。. 例として、STD_LOGIC_VECTOR タイプを整数タイプに変換する場合が挙げられます。.

Integers are not "closely related" to these, so need a conversion function to_integer. When using the conv_std_logic_vector VHDL function to convert a signed integer to a std_logic_vector, XST does not sign extend the sign bit.
