- Always send a response (even empty) to prevent client timeouts
- Add pandas-stubs to dev dependencies for mypy type checking
- Server now sends newline-terminated response for all commands
This fixes the mypy CI failure. Integration test failures still need
investigation - likely due to event loop blocking when mixing sync/async.
- Use X | None syntax instead of Optional[X] (UP045)
- Sort imports in dashboard app (I001)
- Remove unnecessary UTF-8 encoding argument (UP012)
- Add 'from err' to exception re-raises (B904)
- Remove unused imports in integration tests (F401)
- Fix useless expression in test (B018)
- Cast **1.5 result to float in LDO model (mypy no-any-return)
- Use functools.partial instead of lambda in server (mypy misc)
InstrumentServer is a general-purpose SCPI-over-TCP server that can
host any device implementing the SCPIDevice protocol (process method).
Moving it from simulation/ to instruments/transport/ reflects this:
- simulation package now depends on instruments package
- InstrumentServer can host both virtual and real instrument adapters
- Added SCPIDevice Protocol for type-safe device registration
Create SimulationServer that wires physics engine to all virtual
instruments and exposes them over TCP. Add 'serve' CLI command to
start the server with configurable ports and physics rate.
Create InstrumentServer class with asyncio for hosting virtual SCPI
instruments over TCP. Supports registering instruments on specific
ports with port-to-instrument mapping.
Implement SCPI-based virtual DMM with DC voltage and current measurement.
Supports MEAS, CONF, and READ commands. Integrates with physics engine
for DUT output measurements.
Implement SCPI-based virtual power supply with voltage/current control
and output enable commands. Integrates with physics engine for DUT
input voltage simulation.
- TEMP:SETPOINT: Set/query target temperature
- TEMP:ACTUAL?: Query actual chamber temperature from physics engine
- TEMP:STAB?: Query temperature stability (within 0.5°C threshold)
Provides SCPI command parsing and dispatch mechanism for virtual
instruments. Includes IEEE 488.2 common commands (*IDN?, *RST, *CLS,
*OPC) and abstract methods for instrument-specific implementations.
Comprehensive test suite for SCPI command parsing:
- SCPICommand dataclass tests (creation, keyword property)
- Parser tests for queries, commands, arguments
- IEEE 488.2 common command tests (*IDN?, *RST, etc.)
- Edge cases (whitespace, empty strings)
- Instrument-specific command tests
Also fixed bug where is_query was determined from command string
ending rather than header ending (handles queries with arguments).
Adds SCPIParser class with parse() method that handles:
- IEEE 488.2 common commands (*IDN?, *RST, etc.)
- Query commands (ending with '?')
- Commands with comma-separated arguments
- Whitespace stripping
- Add time multiplier control (1× to 100× speed)
- Calculate steps based on real elapsed time
- Add 50ms delay to prevent UI thrashing
- Display current speed in Sim Time metric
