Using SpyDrNet Example Netlists

Many EDIF, Verilog, and EBLIF example netlists are found in the SpyDrNet repo under example_netlists. In versions of SpyDrNet previous to 1.13, the example netlists were included in the python package. From version 1.13 on, perform the steps below to access the example netlists using sdn.load_example_netlist_by_name(<name>).

Option 1

  1. Download the example netlists directory from the SpyDrNet repo, or just clone the repo.

  2. In the Linux terminal, run

    export EXAMPLE_NETLISTS_PATH=<path to example netlists>

    where the <path to example netlists> is the path to the top level example netlists directory in the spydrnet repo.

  3. Use the sdn.load_example_netlist_by_name(<name>) to access the example netlist. For example:

    import spydrnet as sdn
netlist = sdn.load_example_netlist_by_name("b13")

Option 2

Run the following code and type ‘y’ and then hit enter when asked whether or not to download the example netlists.

import spydrnet as sdn
netlist = sdn.load_example_netlist_by_name(<name>)

Additional Information

It is possible to see the names of the example netlists for each netlist format

print(sdn.example_netlist_names) # lists the names of the EDIF example netlists
print(sdn.verilog_example_netlist_names) # lists the names of the Verilog example netlists
print(sdn.eblif_example_netlist_names) # lists the names of the EBLIF example netlists

By default, sdn.load_example_netlist_by_name() assumes the netlists is EDIF format. To load a Verilog or EBLIF example netlist, do the following:

import spydrnet as sdn
from spydrnet.util.netlist_type import VERILOG, EBLIF

verilog_example_netlist = sdn.load_example_netlist_by_name(name, VERILOG)
eblif_example_netlist = sdn.load_example_netlist_by_name(name, EBLIF)
