verdi kdb

生成verdi kdb，可以在下次要打开verdi的时候快速打开design，不用后面每次都进行vericom编译操作。

Examples:

1. Generate the work.lib++ library:

vericom -f run.f

2. Generate the kdb.elab++ elaborated KDB:

elabcom -top system

3. Read the elaborated KDB into Verdi:

verdi -elab kdb.elab++
verdi -elab xxx_path/kdb.elab++

Alternatively, execute the following:

verdi -elab kdb
