For this code: function main() -> unit = { foreach (i from 0 to 10) { print_endline("Clock " ^ dec_str(i)); }; () } I get this SV: function automatic sail_unit main(sail_unit zgsz31); sail_unit sail_return; bit goto_for_start_2 = 1'h0; b...
经过几周的更新,SV核心部分用户自定义类型和包内容已更新完毕,接下来就是RTL表达式和运算符。 马上HDLBits-SystemVerilog版本也开始准备了,基本这一部分完成后就开始更新~ 循环语句允许多次执行编程语句或begin-end语句组。SystemVerilog中的循环语句有:for、repeat、while、do..while、foreach和forever。其中,所有综合编...
SystemVerilog provides the support to useforeachloop inside a constraint so that arrays can be constrained. Theforeachconstruct iterates over the elements of an array and its argument is an identifier that represents a single entity in the array. Click here to refresh loops in SystemVerilog !
'{9,10}};initialbegin// First iterate through the first dimension using "i"foreach(md_array[i])// For each element in first dimension "i", iterate through the// second dimension using "j"foreach(md_array[i][j])$display("md_array[%0d][%0d] = %0d",i,j,md_array[i][j]);...

The structure declaration syntax in SystemVerilog is very similar to the C language. The one difference is that C allows for an optional “tag” after the struct keyword and before the opening brace. SystemVerilog does not allow a tag. ...
To help verification engineers understand design constructs, the always_type blocks are briefly introduced in this section. Enhancements to tasks and functions make them more useful and easier to use. New SystemVerilog operators Enhanced loops & jumping statements always_comb / always_latch / always...
Earlier versions of SystemVerilog required you to use either nested foreach loops to constrain all combinations of array elements so that they would not be equal to each other. Or else repeatedly randomize one element at a time, and then constraining the next element to not be in the list ...

All of these features, and more, are described in this section. New SystemVerilog operators Enhanced loops & jumping statements Logic specific processes (always_type blocks) document designer intent always_comb always_latch always_ff Added design checks using always_type blocks always @* -vs- ...
