3. Schematic Editor API

Module: typhoon.api.schematic_editor

Schematic API provides set of functions/methods to manipulate existing schematic models (tse files) and create new ones from scratch programmaticaly. This is most commonly used for creating scripts for testing and automating repetitive tasks, but its use is not restricted for these use cases only.

3.1. Examples

Following two examples illustrates how you can use Typhoon Schematic Editor API.

3.1.1. Example 1

This example illustrates creating model from scratch, saving it and compiling it as a last step.

import os
from typhoon.api.schematic_editor import SchematicAPI

sys.path.insert(0, os.path.split(os.path.abspath(os.path.join(os.path.realpath(__file__), '..','..', '..','..')))[0])

model.save_as(file_name)

# Compile model
if model.compile():
    print("Model successfully compiled.")
else:
    print("Model failed to compile")

# Close the model
model.close_model()

Script output:

Setting component properties...
Saving model to 'RLC_example.tse'...
Model successfully compiled.

After executing this script, model is saved in a file “RLC_example.tse in directory where script is located.

Following image shows how model looks like if opened in Typhoon Schematic Editor.

3.1.2. Example 2

This example ilustrates loading an existing model (created in previous example) and modyfing it, saving changes and compiling it as a last step.

import os
from typhoon.api.schematic_editor import SchematicAPI

sys.path.insert(0, os.path.split(os.path.abspath(os.path.join(os.path.realpath(__file__), '..','..', '..','..')))[0])

# Create SchematicAPI object
model = SchematicAPI()

# Load the model from file
print("Loading model...")
model.load("RLC_example.tse")

# Starting coordinates
x0 = 8192
y0 = 8192

print("Modifying model...")
# Get the handler for Rin component
r_in = model.get_item("Rin", item_type="component")
if r_in:
    # Delete the component
    model.delete_item(r_in)

# Get the handler for I component
i_meas = model.get_item("I", item_type="component")
if i_meas:
    # Delete the component
    model.delete_item(i_meas)

# Create a contactor component
switch = model.create_component(
    "core/Single Pole Single Throw Contactor",
    name="SW",
    position=(x0-200, y0-100)
)

# Get the component handlers to create connections with the contactor
v_in = model.get_item("Vin", item_type="component")
junction = model.get_item("J2", item_type="junction")

# Create the connections
model.create_connection(model.term(v_in, "p_node"), model.term(switch, "a_in"))
model.create_connection(model.term(switch, "a_out"), junction)

# Get the handler for RC Load subsystem
rc_load = model.get_item("RC Load", item_type="component")

# Get the handler for R component inside the RC Load subsystem
r = model.get_item("R", parent=rc_load, item_type="component")

# Read and change the resistor value of R component
old_r_value = model.get_property_value(model.prop(r, "resistance"))
new_r_value = old_r_value * 10
model.set_property_value(model.prop(r, "resistance"), new_r_value)

# Save the model
print("Saving model...")
model.save()

# Compile model
if model.compile():
    print("Model successfully compiled.")
else:
    print("Model failed to compile")

# Close the model
model.close_model()

Script output:

3.5. API references

class SchematicAPI(*args, **kwargs)

Class models schematic model and provide methods to manipulate schematic model.

Get item handle for item named name from parent parent_handle.

Note

parent is optional if not specified root scheme will be used.

Note

item_type is optional parameter, it can be used to specify type of item to get handle of. It accepts constant which defines item type (See Schematic API constants)

Parameters:

• name (str) – Item name.

• parent (ItemHandle) – Parent handle.

• item_type (str) – Item type constant.

Returns:

Item handle (ItemHandle) if found, None otherwise.

Raises:

• SchApiException –

• 1. if there is multiple items found, for example –

• component has sub-component named exactly the same as component –

• terminal. In that case specify item_type to remove ambiguity. –

• 2. if items from locked component are requested. –

# set_terminal_sp_type indirectly sets terminal sp type, terminal sp type
# resolver will in time of compilation calculate sp type value, which can
# be also set directly using set_terminal_sp_type_value (see example below)
#
const1 = mdl.create_component("core/Constant", name="Constant 1")
mdl.set_terminal_sp_type(mdl.term(const1, "out"), "int")

unlink_component(item_handle)

Unlinks component, breaking link from component to its library implementation. This allows model with this component to be shared freely without providing thatt particular library, as component implementaion is transfered from library to model component.

item_handle (ItemHandle) – Component item handle object.

Returns:

None

Raises:

• SchApiException - when some of following occurs –

• Component is an atomic component. –

• Component is already unlinked. –

• One or more component parent are linked. –

• Component is locked or some parent/s are locked. –

• SchApiItemNotFoundException when component can't be found. –

Example:

#
# Demonstrate use of term function.
#
from typhoon.api.schematic_editor import SchematicAPI
mdl = SchematicAPI()
mdl.create_new_model()

grid_fault = mdl.create_component("core/Grid Fault")
mdl.unlink_component(grid_fault)

warning(msg, kind='General warning', context=None)

Signals some warning condition.

• context (ItemHandle) – Handle for context item.

Returns:

None

Raises:

SchApiItemNotFoundException if context item can't be found. –

Example:

#
# Demonstrate use of warning.

if mdl.get_property_value(resistance_prop_handle) < 0.0:
    mdl.warning(msg="Resistance value is negative",
                context=resistance_prop_handle)
