Digital module P128C200M, the PIN electronics device implemented in the open standard AXIe-1.
The P128C200M module provides measurement and control of integrated circuit parameters using parametric measurement methods, as well as functional and algorithmic control. The module implements a synchronization system that ensures the operability of a group of modules when they are installed in the AXIe-1 chassis.
Parametric measurement methods are implemented on the basis of special PPMU meters that provide generation and measurement of parameters of DC electrical signals. Each channel of the module contains its own independent PPMU, which is why parallel (simultaneous) control of DC parameters is provided on all channels of the module.
For parametric measurements on the signal pins of the chips, the module provide
  • formation of a programmable constant voltage value and measurement of constant voltage and DC power (FVMV, FVMI modes);
  • formation of a programmable value of DC power in 5 ranges and measurement of DC voltage and DC power (FIMV, FIMI modes);
  • measurement of DC voltage in the disconnected state (FNMV mode);
  • limiting the DC voltage value by two independent programmable levels, in FIMI and FIMV modes;
  • limitation of the DC power value, by two independent programmable levels, in each current range, in FVMV, FVMI modes
Functional control methods are implemented on the basis of test generators and PIN-electronics devices that provide formation and control of a vector sequence of pulse signals, as well as measurement of dynamic parameters of chips. Test generators and PIN electronics devices are programmed independently for each channel and can operate in different frequency domains (up to 4 domains per module) and test sequence generation modes (universal and algorithmic modes). Additionally, the test generator provides a scanning mode and increases (multiplies) the maximum length of the vector sequence by redistributing the test memory between channels.
For functional monitoring and measurement of dynamic parameters on the signal pins of the chips, the module provides:
  • generation by channel drivers of a vector sequence of pulse signals with programmable voltage levels (lower, middle, upper, and high-voltage levels), the steepness of the front and cutoff of the signal, and timestamps for switching between voltage levels (timestamps D0, D1, D2).
  • channel Comparators monitor the state of signals in vectors by comparing the voltage levels of signals in vectors with the programmable voltage levels of Comparators at specified time points (timestamps R0, R1);
  • programmable connection for signal monitoring and disconnection for dynamic active load signal generation, with programmable levels of positive current, negative current, and switching voltage;
  • programmable connection during signal monitoring and disconnection during signal generation of dynamic voltage limiters on channels with programmable upper and lower voltage levels;
Modular design in accordance with the AXIe-1 standard, a high number of measurement channels and their precision characteristics allow you to measure and control parameters of a sufficiently large area of integrated circuits based on a single module in the AXIe-1 crate. The module synchronization system, based on the signals and functions of the AXIe-1 standard, allows you to create automatic test equipment systems based on a group of modules and air-cooled, for measuring and monitoring chips with a large number of signal pins. The unified software allows for automated diagnostics and calibration of all device parameters, as well as ensures that all measurement and parameter control processes are performed when testing integrated circuits.
The listed functionality and characteristics of the device are superior to domestic analogues and are comparable to foreign products.
