Cadence最新数字电路验证工具(xrun)

一、Cadence最新数字电路验证工具(xrun)
现在Cadence又开发出了新的仿真工具，叫xcelium，代表工具，xrun。

1.1、xrun仿真环境搭建
环境变量设置

#!/bin/tcsh -fv

module load Verdi/201509SP2-4

#Xcelium RD Option Setting Begin
setenv CADENCE_ENABLE_VASREQ_12055_PHASE_1
setenv CADENCE_ENABLE_VASREQ_6114_PHASE_1
setenv CADENCE_ENABLE_VASREQ_6114_PHASE_2
setenv CADENCE_ENABLE_VASREQ_6114_PHASE_3

setenv CADENCE_ENABLE_VASREQ_19619_PHASE_1
setenv CADENCE_ENABLE_VASREQ_44905_PHASE_1
#setenv CADENCE_ENABLE_VASREQ_63188_PHASE_1

setenv LD_LIBRARY_PATH ${VERDI_HOME}/share/PLI/IUS/linux64/boot/:${LD_LIBRARY_PATH}

#Xcelium RD Option Setting end

#Xcelium RD Option Setting Begin
module load IUS/2003_e145
module load JasperGold/1912
#Xcelium RD Option Setting end

Simulation Command

my $sim_option = "xrun -64bit -licqueue -elaborate -access +rwc -timescale 1ns/1ps -uvm
-uvmnoatuocompile -sv -sysv_ext +.h+.sv+.svh+.svi+.pkg ";
$sim_option .= " +define+XCELISUM_SIM "; ##To avoid array func etc
$sim_option .= " -nowarn CUVIRH ";
$sim_option .= " -nowarn FUNTSK ";
$sim_option .= " -nowarn STARMT ";
$sim_option .= " -warn_multiple_driver ";
$sim_option .= " -xmerror BNDWRN ";
$sim_option .= " -dumpports_format 2 ";
$sim_option .= " -v2009 -race ";
$sim_option .= " -top top";
$sim_option .= " -ALLOWREDEFINITION ";
$sim_option .= " -coverage A -covdut top ";
$sim_option .= " -f list_verdi.f ";
$sim_option .= " -input ucli.do "; #tcl file,Dump wavefrom, Ctrl File
$sim_option .= " -loadpli1 $ENV{VERDI_HOME}/share/PLI/IUS/linux64/boot/debpli.so:novas_pli_boot ";

Control File(tcl)

set fsdn_fn $env(TESTNAME).fsdb; #name of the wavefron file
set log_fn $env(TESTNAME).fsdb.log; #name of the log file
set mbyte_cnt 1000; #limit on the wavefrom filesize
set file_cnt 100; #limit on the number filesize

call fsdbAutoSwitchDumpfile mbyte_cnt "$fsdb_fn" $file_cnt "$log_fn";
call fsdbDumpvars 0 top
call fsdbDumpSVA
run; #

#exit;
#quit;
#run 2 ms;
#run 3us;
#stop -absolute 300 ns;
#call $fsdbDumpoff;
#call $fsdbDumpon;
#call $fsdbDumpSuppress(tb.d);
#call $fsdbDumpMenInScope(0, tb.d);
#call $fsdbDumpMDAOnChange(2, tb.d);
#call $fsdbDumpflush;
#call $fsdbDumpStrength;
#do fn.tcl
exit;

1.2、xrun使用经验总结
irun工具，提供了 –gateloopwarn 选项，用于检测这种零延时的组合逻辑。
