Overview

The Sine Wave Frequency Generator is a time and frequency aligned sine wave frequency generator allowing any frequency to be generated between 1Hz and 200kHz adjustable in 1Hz steps. It uses the vendor's Adjustable Clock core as source for source synchronous frequency generation. It provides either a parallel DAC interface or a serial highly configurable SPI interface to access a DAC.

The IP core comes with a Linux Driver (the same driver as for the Frequency Generator)

Key features

  • Configurable frequency signal generation (1-200kHz (depends on DAC sampling rate))
  • Configurable polarity (positive or negative zero crossing and PPS boundary)
  • Output delay compensation
  • Alignment of the frequency generator to an input time (frequency and phase)
  • Automatic realigning of the frequency generator on time jumps and frequency changes
  • Continuous generation until disabled
  • Configurable DAC Sample width
  • Configurable DAC Sampling rate
  • Optional DAC Sample scaling
  • Optional DAC Sample offset
  • SPI DAC Controller
  • AXI4Lite register set or static configuration

Generating multiple clock frequencies using Specman "real" feature in mixed (Analog/Digital) design environments

Using our “Specman agent approach for the Mixed Verification” along with exploiting “real” feature of Specman version 8.2, we can introduce directed/constrained randomization to the frequencies needed for the analog modules which are interacting with the DUT (Design Under Test). This approach gives complete controllability over the clock frequencies, which can be directly randomized and modified on-the-fly from the testcase, as the scenario may demand.

M31 on the Specification and Development of MIPI Physical Layer

MIPI is the abbreviation of "Mobile Industry Processor Interface". This article will introduce the physical layer specifications of MIPI architecture, and explain the features and benefits of D-PHY and C-PHY respectively. Then, the MIPI perspective on the development and challenges of automotive electronics and the professional MIPI technical services that M31 can provide will be shared.

Silicon-Accurate Fractional-N PLL Design

Fractional-N PLLs are a useful class of PLLs and not well understood. This paper explains in simple terms how these differ from a regular integer PLL. Common applications are listed along with a brief description of the key performance parameter – jitter.

FPGA Implementation of DLX Microprocessor With WISHBONE SoC Bus

DLX is an open source microprocessor, it’s free and it has never been implemented in a commercial ASIC (Application Specific Integrated Circuit) design. The objective of this project is to use the DLX microprocessor implemented with Wishbone bus interface for a SoC (System-on-Chip) design.

Mixed Signal Drivers for Ultra Low Power and Very High Power Applications

Evolving niche markets, such as ICs for biomedical applications, are very challenging in respect to power consumption and on chip power dissipation, namely, wide range from ultra low power (ULP) functionality (<uW) where IC is battery powered, e.g. mobile micro transducers, to very high power (VHP, >5W), e.g. coded energy transfer from RFID¡¯s for remote sensing and animal tracking.
