Verilog$timeformatsystem function specifies%tformat specifier reporting style in display statements like$displayand$strobe. Syntax $timeformat(<unit_number>,<precision>,<suffix_string>,<minimum field width>); unit_numberis the smallest time precision out of all`timescaledirectives used in source code...
I am curious about the difference when using a format specifier for printing in real-time. Please correct me if I am mistaken, but I think it prints 1000 (10 *10ps = 1000 ns) due to time precision. However, I would like to know the reason behind this discrepancy. Solution: The MSDT...
$display的打印选项: IEEE Std 1800™-2012:The%pformat specifier may be used to print aggregate expressions such as unpacked structures,arrays, and unions. 常用形式: 小数计算场景: int i_tmp=3; real r_real_ab; real r_real_a = 1; real r_real_b = 2; i_tmp = real'(1/3); // 结...
Negative numbers can be specified by putting a minus sign before the size for a constant number, thus they become signed numbers. Verilog internally represents negative numbers in 2's complement format. An optional signed specifier can be added for signed arithmetic. ...

user_string的格式应为“ plusarg_string format_string”,其中格式字符串与$ display任务相同。 这些格式标识符用于将通过命令行提供的值转换为给定格式并存储在变量中。 Example// Note FS : Format Specifiermodule tb;initial begin string var1,var2;bit[31:0]data;if($value$plusargs("STRING=%s",var1)...
