QNet#
- class QNet[source]#
Use DataFrame to hold Net Information about the connected pins of a design.
There is one unique net_id for each connected pin.
Hold the net information of all the USED pins within a design.
Attributes
- net_info#
Provide table of all nets within the design.
- Returns:
Table of the net of pins within design.
- Return type:
pd.DataFrame
- qnet_latest_assigned_id#
Return unique number for each net in table.
- Returns:
For user of the design class to know the lastest id added to _net_info.
- Return type:
int
Methods
- add_pins_to_table(comp1_id: int, pin1_name: str, comp2_id: int, pin2_name: str) int[source]#
Add two entries into the _net_info table. If either component/pin is already in net_info, the connection will NOT be added to the net_info.
- Parameters:
comp1_id (int) – Name of component 1.
pin1_name (str) – Corresponding pin name for component1.
comp2_id (int) – Name of component 2.
pint2 (str) – Corresponding pin name for component2.
- Returns:
0 if not added to list, otherwise the net_id
- Return type:
int
- delete_all_pins_for_component(component_id_to_remove: int) set[source]#
Delete all the pins for a given component id.
- Parameters:
component_id_to_remove (int) – Component ID to remove
- Returns:
All deleted ids
- Return type:
set
- delete_net_id(net_id_to_remove: int)[source]#
Removes the two entries with net_id_to_remove. If id is in _net_info, the entry will be removed.
- Parameters:
net_id_to_remove (int) – The id to remove.
- get_components_and_pins_for_netid(net_id_search: int) DataFrame[source]#
Search with a net_id to get component id and pin name.
- Parameters:
net_id_search (int) – Unique net id which connects two pins within a design.
- Returns:
Two rows of the net_info which have the same net_id_search.
- Return type:
pandas.DataFrame
