c - Verilog 中的 $display 和 C 中的 printf

Question

如您所知，在 Verilog 中有 $display、$strobe 和 $monitor 用于在屏幕上显示文本。在 C 中，printf 也可以在屏幕上显示文本。

我的问题是如何使用其中之一 ($display,$strobe,$monitor)，例如 C 中的 printf？

a: $display
b:$strobe
c:$monitor
d: all of them
e: other

$display("<format>", exp1, exp2, ...);  // formatted write to display
format indication %b %B binary
                  %c %C character (low 8 bits)
                  %d %D decimal  %0d for minimum width field
                  %e %E E format floating point %15.7E
                  %f %F F format floating point %9.7F
                  %g %G G general format floating point
                  %h %H hexadecimal
                  %l %L library binding information
                  %m %M hierarchical name, no expression
                  %o %O octal
                  %s %S string, 8 bits per character, 2´h00 does not print
                  %t %T simulation time, expression is  $time
                  %u %U unformatted two value data  0 and 1 
                  %v %V net signal strength
                %z %Z unformatted four value data  0, 1, x, z

escape sequences, quoted characters in strings \n   newline
                                               \t   tab
                                               \\   backslash
                                               \"   quote
                                               \ddd octal
                                               %%   percent

any other characters between the quotes are displayed
the expressions are taken in order of the format indication
,, in the expression list inserts one space in the output
