10.20 Parser Tracing Functions
Parser tracing functions are debug tools that allow you to follow the generation process. These
functions track script generation procedures and allow you to observe instruction generation and
the changes of values of variables and template structures. Because the Voyager USB 3.0
Exerciser can create sophisticated and dynamic generation scripts, these functions are helpful in
debugging.
Note: These functions have no affect on the compiled firmware instruction output. They only
follow the paths taken in scripts to create instructions or values of variables and template
structures.
10.20.1 PTrace( ) : Parser Trace
Format
PTrace( )
Parser Trace without any supplied parameters outputs the line number from which it was called to
the compilation output window.
PTrace(
“output_string” )
Parser Trace with a supplied string parameter outputs the supplied string to the compilation
output window when called.
Example
50: Main
51: {
52: PTrace ()
53:
Send TX_PACKET
54: {
55: Data = {
AA BB CC DD }
56: }
57: PTrace (“Sending Second TX_PACKET”)
58:
Send TX_PACKET
59: {
60: Data = {
EE FF 00 11 }
61: }
62: PTrace ()
63: }
