Printing packed structs in System Verilog

Question

I have a packed struct defined as shown below

typedef struct packed {
    logic bit1;
    logic [7:0] byte1;
} MyPackedStruct;

MyPackedStruct myPackedStruct;

Is there any SV built in function that I could use to print the structures similar to above but having many more fields, without having to write my own method to print each of the fields using a

$display(...,myPackedStruct.field_name)?

Answer 1

You can use %p - pretty print:

$displayb("%p",myPackedStruct);

'{bit1:x, byte1:xxxxxxxx}

which will print it as an assignment pattern, but you will not be able choose the fields or their ordering, or apply any other individual formating. %p is good for quick and easy displays, but most people eventually wind up writing a method to format it exactly the way they want it.
