Reference

The examples in the previous section has some details on useful built-in modules in CircuitBrew to help you build and generate stimuli for your circuit. This page is a comprehensive list on the gates and environment modules provided, with links to the API, if you need more information on how to use them or extend them.

Built-in circuit modules

Module	Description
circuitbrew.gates.Inv	Inverter
circuitbrew.gates.NorN	N-input NOR
circuitbrew.qdi.Celement2	2-input c-element
circuitbrew.qdi.Wchb	1-bit 4-phase half buffer

Environent modules

These modules are useful for setting up a simulation environment to generate input stimuli and output verification during a SPICE simulation. Most of these are covered in the different examples.

Module	Description
circuitbrew.elements.VoltageSource	Voltage source (usually easier to use Supply)
circuitbrew.elements.Supply	Vdd and GND sources
circuitbrew.elements.ResetPulse	Step waveform useful for applying resets
circuitbrew.elements.VerilogClock	Generate clocks using a Verilog-A instance
circuitbrew.elements.VerilogSrc	1-bit Verilog-A source for input vectors
circuitbrew.elements.VerilogBucket	1-bit Verilog-A sink/verification for output vectors
circuitbrew.qdi.VerilogSrcE1of2	1-bit dual-rail w/ enable Verilog-A source for input vectors
circuitbrew.qdi.VerilogBucketE1of2	1-bit dual-rail w/ enable Verilog-A sink/verification for output vectors
