其他类似的转换还有$realtobits(),$shortrealtobits();$bitstoreal(),$shortbitstoreal()。函数名即表示了其含义~ 此外还有两个有符号和无符号之间的转换函数:$signed(),$unsigned()。 还有一个非常重要的$cast函数,后续有机会单独介绍。 发布于 2022-01-19 21:37...
符号转换的语法如下: 1signed’(expression)2unsigned’(expression) 一些符号转换的例子如下: 1sum =signed’(a) +signed’(a);//cast operands2if(unsigned'(a-b) <= 5) // cast intermediate result3... system verilog的符号转换操作符与verilog的系统函数$signed和$unsigned功能一样。符号转换是可综合的...

Also, to convert between signed and unsigned numbers. Use $signed and $unsigned. Example: wire signed [3:0] a_sign; wire [3:0] b_unsign; assign a_sign = $signed(b_unsign); assign b_unsign = $unsigned(a_sign); Share Improve this answer Follow answered Nov 29, 2023 a...
