generate fsdb file

(1) config
$NOVAS_HOME: VERDI install dir
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$NOVAS_HOME/share/PLI/lib/LINUX:$NOVAS_HOME/share/PLI/IUS/LINUX/boot"
(2) code in testbench
//Enable dump fsdb
initial
begin
$fsdbDumpfile(“test.fsdb”);
$fsdbDumpvars(0,TB);
end
(3) compile/elab/simulation option
irun -access +rwc -loadpli1 debpli:novas_pli_boot -f XXXXXXX.f
