What is the usage of null range in VHDL?

Nettet25. jul. 2024 · If the std_logic_vector range is defined in such a way that its number of elements come to 0 or less than it, the array is said to have a null range. I am sure this is possible with any array in VHDL. Now my simulator tool does give a warning for when this happens. However, I am wondering, why is null range allowed in VHDL? Nettet12. des. 2024 · 2 回答. 不，VHDL数组中的所有元素都是相同的，因此如果元素是 std_logic_vector ，则具有相同的宽度（长度） . 但是在综合中，如果你声明具有最大所需长度的元素，然后只是不使用某些元素的高位，那么任何合适的综合工具都会减少实现中的实际大小 . 如果您的 ...

Nettet8. mar. 2010 · An integer array (with a range to control the bit width) would be possible as well. By the way, the arithmetic types generally have a downto bit order, thus a std_logic_vector (0 to N-1) would be supplied with inverted bits.
