ieee754.part_mul_add.test.test_mul_pipe module

Unit tests for Buffered and Unbuffered pipelines

contains useful worked examples of how to use the Pipeline API, including:

• Combinatorial Stage “Chaining”
• class-based data stages
• nmigen module-based data stages
• special nmigen module-based data stage, where the stage is the module
• Record-based data stages
• static-class data stages
• multi-stage pipelines (and how to connect them)
• how to use the pipelines (see Test5) - how to get data in and out

class ieee754.part_mul_add.test.test_mul_pipe.ExampleAddRecordPlaceHolderStage

Bases: object

example use of a Record, with a placeholder as the processing result

ispec()

returns a Record using the specification

ospec()

process(i)

process the input data, returning a PlaceHolder class instance with attributes that exactly match those of the Record.

record_spec = [('src1', 16), ('src2', 16)]

class ieee754.part_mul_add.test.test_mul_pipe.PlaceHolder

Bases: object

class ieee754.part_mul_add.test.test_mul_pipe.Test5(dut, resultfn, data=None, stage_ctl=False)

Bases: object

rcv()

send()

class ieee754.part_mul_add.test.test_mul_pipe.TestInputMul(a, b)

Bases: object

the eq function, called by set_input, needs an incoming object that conforms to the Example2OpClass.eq function requirements easiest way to do that is to create a class that has the exact same member layout (self.op1, self.op2) as Example2OpClass
