kqcircuits.simulations.flip_chip_connector_sim

class kqcircuits.simulations.flip_chip_connector_sim.FlipChipConnectorSim(layout, **kwargs)[source]

Bases: kqcircuits.simulations.simulation.Simulation

Initialize a Simulation.

The initializer parses parameters, creates a top cell, and then calls self.build to create the simulation geometry, followed by self.create_simulation_layers to process the geometry so it is ready for exporting.

Parameters

layout – the layout on which to create the simulation

Keyword Arguments

**kwargs –

Any parameter can be passed as a keyword argument.

In addition, cell can be passed as keyword argument. If cell is supplied, it will be used as the top cell for the simulation. Otherwise, a new cell will be created. See Simulation.from_cell for creating simulations from existing cells.

build()[source]

Build simulation geometry.

This method is to be overridden, and the overriding method should create the geometry to be simulated and add any ports to self.ports.

ports: List[kqcircuits.simulations.port.Port]
PCell parameters:

  • face_stack (List) - The parameter can be set as list of lists to enable multi-face stack-up on substrate surfaces. Set term to empty list to not have metal on the surface., default=['1t1', '2b1']
