integer类型也是一种寄存器数据类型,integer类型的变量为有符号数,而reg类型的变量则为无符号数,除非特别声明为有符号数,还有就是integer的位宽为宿主机的字的位数,但最小为32位,用integer的变量都可以用reg定义,只是用于计数更方便而已。reg,integer,real,time都是寄存器数据类型,定义在Verilog中用来保存数值的变量,和...
SystemVerilog 不仅支持 Verilog 所支持的所有数据类型,而且还具有诸多其它二态数据类型。现代测试激励文件中最常用的数据类型是bit、int、logic和byte。 整数 Integer 指不含小数部分的数字,即“整数”。SystemVerilog 具有三种类型的有符号数据类型用于保存整数值,这些数据类型各自大小不同。最小的是shortint,范围介于 ...
如果无符号数的位数小于size,那么就在左端扩展:如果最左边的位是0或1,左端就补0扩展;如果最左边的位是x,左端就补x扩展;如果最左边的位是z,左端就补z扩展。 如果无符号数的位数大于size,那么就在左端截去多余的位。 在Verilog-2001中,对于没有size限定的数,那么就在左端按照表达式的size根据最左边的位进行扩展...

Hello, I am using NC-VHDL and trying to port map a verilog file in the VHDL enviroment. I am not able to convert an integer port which is present in the original file. Is there any workaround for this in Verilog ? I have tried using [15:0] array also a [31:0] array but there...
