ATC Analog App

An application to mimic an oscilloscope containing a waveform, showing the measured analog channel on the left and showing readings or data on the right.

Product Overview

The ATC Analog App is a standalone utility application tool that allows the ATC to be used as a general purpose data acquisition device. While most of our test solutions revolve around using the ATC in conjunction with our automated test software, the ATC Analog App allows the user to run the ATC manually for a variety of specific functions. These include a multi-channel oscilloscope, digital logic analyzer, digital output generator, and an analog function generator.

​

Features

  • Seamless graphic user interface

  • Multi-channel oscilloscope with easy channel configuration

  • User-friendly arbitrary waveform generator

  • Digital logic analyzer features to decode various protocols

  • Calibration tool for easy user calibration and probe tuning

  • Arbitrary digital message generator

FPGA Intellectual Property Cores

Xilinx Compatible
SLVS-EC IP Core

Product Overview

Our SLVS-EC (Scalable Low-Voltage Signaling with Embedded Clock) Core utilizes standard Xilinx GTP transceivers to capture and decode high-speed serial data conforming to the JIIA SLVS-EC standard. This module enables FPGA code developers to easily integrate the latest high-speed camera chips into their designs.

​

Features

  • Embedded C driver APIs included

  • Compatible with most Xilinx Zynq family SoCs

  • Specific support for IMX-426 camera chip

Product Overview

Our AXI Controller Area Network (CAN) core enables CAN messages up to 32 bits for any bus. Our custom CAN core can be used without AXI interface and integrated directly with a user's custom logic.

Features

  • Embedded C driver APIs included

  • Includes CAN transfer layer with registers mapped to an AXI 4 Lite slave interface

  • Highly configurable IP core

  • Compatible with most Xilinx SoCs

AXI CAN IP Core

Products - FPGA IP Cores

AXI DAC Driver IP Core

Product Overview

The AXI Digital to Analog Converter (DAC) driver core processes low level signaling and forwards the received data. Our DAC driver core consists of a SPI core, a command/data buffer per channel, a timer, control logic, and can be operated on AXI or a user's custom logic.

​

Features

  • Capable of handing multiple DACs simultaneously 

  • Capable of operating with design rule checking (DRC) using serial or parallel interfaces

  • Comes with set of drivers for embedded processors 

  • Includes buffer of commands and data points to hold the waveform for each DAC channel

  • Timer updates all DAC channels at a specified sample period

    • When timer expires, the queued values in all enabled DAC channels transfer to the DAC output register

    • User ensures the timer runs sufficiently for all enabled channels to be updated (24-bit SPI transaction per channel)

AXI SPI Master IP Core

Product Overview

The AXI Quad Serial Peripheral Interface (SPI) core connects the AXI4 interface to those SPI slave devices that support the Standard, Dual, or Quad SPI protocol instruction set. Our custom SPI core can handle multiple slaves and can act as both a master and slave device.
