VCS/Xcelium dump fsdb

Demo

set fsdb_fn top.fsdb; #$env{TSNANE}.fsdb

set log_fn top.fsdb.log;

set mbyte_cont 1000; 

set file_cnt 30;

Xcelium:

call fsdbAutoSwitchDumpfile $mbyte_cnt \"$fsdb_fn\" $file_cnt \"$log_fn\"

call fsdbDumpvars 0 top

run; quit;

VCS:

call \$fsdbAutoSwitchDumpfile($mbyte_cnt, \"$fsdb_fn\", $file_cnt, \"$log_fn\")

call {$fsdbDumpvars(0, top)};

Questa:

fsdbAutoSwitchDumpfile $mbyte_cnt $fsdb_fn $file_cnt $log_fn

fsdbDumpvars 0 top;

二维数据

在dump fsdb的地方加上

$fsdbDumpfile(test_fsdb);

$fsdbDumpvars(0, "+all", tb_top);

$fsdbDumpon();

// dump assertion waveform

$fsdbDumpSVA;

在vcs command需要加(legacy option)：

-P $VERDI/share/PLI/VCS/LINUX64/novas.tab $VERDI/share/PLI/VCS/LINUX64/pli.a

FSDB Dump Command in Verilog

Supported Simulators for FSDB Dumping Commands

General Dumping Commands

$fsdbDumpfile

$fsdbDumpfile("FSDB_Name" | FSDB_Name_var [ ,Limit_Size | ,Limit_Size_var ]);

$fsdbDumpFinish

This command closes all FSDB files in the current simulation and stops dumping of signals. 

$fsdbDumpflush

This command forces the signal values to be flushed to the FSDB file while the simulation is running.

NOTE: The Novas object files for FSDB dumping automatically flushes the value change data to the FSDB file on the disk based on following conditions:
- The simulation stop is due to a $stop statement in the design.
- The simulation stops at a user specified breakpoint.
- The user uses Ctrl-C to break the simulation.

$fsdbDumpon, $fsdbDumpoff

$fsdbDumpon([ "option"| option_var| ]);

$fsdbDumpoff([ "option"| option_var]);

$fsdbDumpvars

$fsdbDumpvars([ depth, | "level=",depth_var, ] [instance | "instance=",instance_var] [ ,"option" | ,"option=",option_var ]*);

option: "+mda", "+all", "+fsdbfile+filename"

$fsdbDumpvars(1, "instance=", instance_string);

Use Environment Variable(s) in the String Argument

setenv MY_FSDB_FILE_PATH /home/test

setenv MY_FSDB_FILE test

$fsdbLog

$fsdbLog(["label"], ["message"], [severity], ["stream_name"] [["format"]*, variables | "string"]* );

$fsdbLog( , , , , var1);

$fsdbDumpSVA

包括fsdbAutoSwitchDumpfile

fsdbDump用法 | Francis's blog (francisz.cn)

FSDB Dumping Command Line Options

Option	Description	Example
+fsdb+all[=on|off]	Enables dumping of all signals including memory, MDA, packed array, structure, union, power-related, and packed structure in all scopes specified in $fsdbDumpvars or the entire design if no scope is specified. The default is off.	+fsdb+all=on
+fsdb+autoflush	Enables the automatic flush function when the simulation is stopped with the $stop dumping command or by using the Ctrl-C shortcut key. This option is useful when dumping the FSDB file in batch mode and to view the results on nWave immediately.	+fsdb+autoflush
+fsdb+dump_log [=on|off]	Enables/disables novas_dump.log. The default is on.	+fsdb+dump_log=on

eg: simv +fsdb+dump_log=off可以关闭novas_dump.log

使用TCL

编写ucli.do

  fsdbDumpfile test.fsdb

  fsdbDumpvars 0 tb_top

  fsdbDumpvars 0 top.instance

  run

 vcs ucli -i ucli.do

xrun -input ucli.do

demo:

#run 0
#show
#set name [get tb_top.testname]
#dump -file $name.fsdb -type FSDB
#dump -add tb_top -depth 0 -fsdb_opt +sva -aggregates -fid FSDB0

run

########################################
#### call {cmd}
#### call {$fsdbDumpvars(0, tb_top)};

#### dump after a break
#fsdbDumpfile break.fsdb
#fsdbDumpvars 0 top
#fsdbDumpoff
#stop -file tb.v -line 13 -once -continue -command {fsdbDumpon}
#run
#quit

verdi加载kdb

vcs编译时，加上“-kdb -lca”选项，就可以生成simv.daidir/kdb.elab++这个目录。

verdi打开时，使用“verdi -elab simv.daidir/kdb”命令来打开
