Test Plan changes for PLT-300A

Test plans written for the PLT-200A are expected to work as-is when used with the PLT-300A.

ground command

A new ground command has been added, to allow specifying which DUT ground signals should be connected to the PLT system ground.

measure command changes

The measure command has been extended to support additional measurement channels, which are not available on PLT-200A:

channel

Description

current1V8

1.8V current draw, using ADC

currentDMM

Current draw, using DMM

voltageDATP00

DATP00 voltage, using ADC

voltageDATP01

DATP01 voltage, using ADC

voltageDATP02

DATP02 voltage, using ADC

voltageDATP03

DATP03 voltage, using ADC

voltageDATP04

DATP04 voltage, using ADC

voltageDATP05

DATP05 voltage, using ADC

voltageDATP06

DATP06 voltage, using ADC

voltageDiff

Differential voltage, using ADC

voltageDMM

Voltage, using DMM

power command changes

The power command has been extended to support the additional voltage rails available in the PLT-300A:

rail

Description

1V8

1.8V power rail

24V

24V power rail

In addition, power command now allows setting the SWD and JTAG signaling voltage to either 1.8 or 3.3 Volt.

mux command changes

The mux command has been extended to allow connecting or disconnecting some of the signals from the MUX, digital pin drivers and ADCs that only tolerate up to 5V:

signal

Description

DATP00…DATP06

Direct Analog Test Probes

DDTP00…DDTP08

Direct Digital Test Probes

PPC Changes

  • Pogo-Pin Cassettes (PPCs) designed for PLT-200A do not separate DUT ground (GND1, GND2, GND3 and GND4) from the PLT system ground. Connecting such a PPC through the HD78 will cause DUT grounds to be shorted with the PLT GND signal.

Missing TP/UART Switch

  • On PLT-300A, it is not possible to switch UART0 signals with DDTP15/DDTP16 and DATP08/DATP09. DDTP15 and DDTP16 are not available.
