WebMay 15, 2024 · Natural: 32 bit unsigned value starting at 0 Positive: 32 bit unsigned value starting at 1 This is slightly wrong. Integer is implementation defined, so whoever implements the compiler (like mentor, quartus etc) can define it as many bits as they want. So in theory you could have 16, 32 or 64 bit integer, depending on which tool you are using. WebOct 19, 2012 · there are a couple of methods. Convert it to unsigned by implicitly making it an array: ASamplexDY (to_integer ( unsigned' ("" & IsISamplexS) )) <= DxDY; here, the ( "" & IsISamplexS ) makes it an array of length 1, and the unsigned' qualifies it as an unsigned because it could be signed or unsigned.
