The log command will record simulation history in a file. It's similar to the\n\

log [[on|lxt [file_name]]|[off]]\n\
Enables or disables logging. Specify no options to see log status.\n\
The lxt option encodes the log file so that an external viewer\n\
like gtkwave can be used to view the file.\n\
log w|r reg [, expr]\n\
Specify a register to log. See the break command for expression syntax\n\
\n Examples:\n\
\tlog - Display log status\n\
\tlog on - Begin logging in file gpsim.log\n\
\tlog on file.log - Begin logging in file file.log\n\
\tlog lxt - Begin lxt logging in file gpsim.lxt\n\
\tlog lxt file.lxt - Begin lxt logging in file file.lxt\n\
\tlog off - Stop logging\n\
\tlog w temp_hi - Log all writes to reg temp_hi\n";
