# How to debug

## write debug message

* in c++, all debug message should be output with the macro DBG(num, xxxx)

* in python, all debug message should be output with logging.debug(num, xxx)

## enable debug message

* we should put below code at the begin of the user script to enable any debug code. 

```

set—debug—level(num, filename)

```

num should be larger than the macro used in the source code, such as set—debug—level(lOO, 'aa.cc'), 

all debug message in aa.cc were output with DBG(num, xx x) where num < lOO will be print

use set—debug—level(num) without specify the filename, all source files debug message will be enabled.

## show source file name of the debug message

```

show—debug—filename()

```

## vectorless flow correlation between vesper and hvp

1. get pin service

```

>>lt=dv.get—design()

>>cell=lt.get—cell(l625)

>>ps=cell.get—pin—service()

>>pin—data= ps.get—pin—data(64)

>>pin—data

```

2. hvp deubg

attachment:"correlation vesper and hvp.pptx"

```

hvp -regression -wd /**tempfolder /**run.tcl

```

3. vesper debug instance power

在create_view后使用debug_instance=["instance_name",...]

4. gdb hvp:

```

gdb hvp_binary set args *.tcl

b *.cpp:line_number 

wh

run

```
