1. FSDB Dump Command Supported Simulators![]()
2.General Dumping Commands
$fsdbDumpfile("FSDB_Name" | FSDB_Name_var [ ,Limit_Size | ,Limit_Size_var ]);This command closes all FSDB files in the current simulation and stops dumping of signals.
This command forces the signal values to be flushed to the FSDB file while the simulation is running.
- The user uses Ctrl-C to break the simulation.
2.4 $fsdbDumpon
$fsdbDumpon([ "option"| option_var| ]);$fsdbDumpoff([ "option"| option_var]);$fsdbDumpvars([ depth, | "level=",depth_var, ] [instance | "instance=",instance_var] [ ,"option" | ,"option=",option_var ]*);option: "+mda", "+all", "+fsdbfile+filename"$fsdbDumpvars(1, "instance=", instance_string);
Use Environment Variable(s) in the String Argument
$fsdbLog(["label"], ["message"], [severity], ["stream_name"] [["format"]*, variables | "string"]* );$fsdbLog( , , , , var1);
2.8 $fsdbDumpSVA
参考文章《fsdbDump用法》、《fdsb那些事》《将fsdb波形文件dump到多个文件中》
eg: simv +fsdb+dump_log=off可以关闭novas_dump.log
