Simulation / Testing¶
Pyha provides an simple interface for simulations and asserts in order to quickly write unit-tests.
Main idea is to compare the MODEL
output against the hardware simulations.
Simulation¶
Asserts¶
Use the following functions with the assert
statement.
Delays¶
Each register in signal path delays the output by one sample, resulting in a mismatch compared to a software MODEL
.
The delay will be compensated if you specify the delay with self.DELAY
.
Example:
class T(Hardware):
def __init__(self):
self.reg = 0
self.DELAY = 1 # 1 register on signal path (input -> output)
def main(self, a):
self.reg = a
return self.reg
