Fluent Assertions Faces Backlash After Abandoning Open Source Licensing
Fluent Assertions is facing backlash after dropping the Apache license for a commercial model, leaving users blindsided and questioning contributor rights.
Python-based tools and utilites for working with the Vlsir IC design schema.
FIXME! Details here.
VlsirTools includes drivers and result-parsers for popular spice-class simulation engines including:
class SupportedSimulators(Enum):
"""Enumerated, Internally-Defined Spice-Class Simulators"""
SPECTRE = "spectre"
XYCE = "xyce"
NGSPICE = "ngspice"
The primary entry-point for simulation is vlsirtools.spice.sim
. By default, sim
runs your chosen simulator in parallel over the list of SimInputs
provided as inp
.
def sim(
inp: OneOrMore[vsp.SimInput], opts: Optional[SimOptions] = None
) -> OneOrMore[SimResultUnion]:
The sim
function takes as input one or more vlsir.spice.SimInput
s and a set of simulation options (vlsirtools.spice.SimOptions
), and returns one of two result-types depending on its input options
.
class ResultFormat(Enum):
"""Enumerated Result Formats"""
SIM_DATA = "sim_data"
VLSIR_PROTO = "vlsir_proto"
The VLSIR_PROTO
result-format returns a vlsir.spice.SimResult
object, which is a protobuf-encoded representation of the simulation results. The SIM_DATA
format instead uses the types defined in vlsirtools.spice.sim_data
, a python-native combination of dataclasses and numpy arrays. The former is generally more convenient for sharing with other programs, and the latter for further in-Python processing.
Each spice-class simulator includes its own netlist syntax and opinions about the specification for analyses.
