Adjustable Counter Clock core

The Adjustable Clock from NetTimeLogic is an adjustable counter clock with nanosecond resolution (second and nanosecond format).

Overview

The Adjustable Clock from NetTimeLogic is an adjustable counter clock with nanosecond resolution (second and nanosecond format). It is used by all other cores from NetTimeLogic but can also be used as standalone core. It contains a hardware implemented PI servo loop (which also can be bypassed) for smooth adjustment of drift and offset. Drift and Offset correction are adjusted in parallel and individual. It can take any input frequency, even with non-integer clock periods (e.g. 66MHz) which is handled with fractional subcounters. It has multiple adjustment inputs which are multiplexed to define the source of synchronization.

All calculations and corrections are implemented completely in HW.
The IP core comes with a Linux Driver

Key features

    • 32 bit second and 32 bit nanosecond counter clock with fractional extention

    • Allows non-integer clock periods
    • Multiplexing of multiple adjustment inputs
    • AXI4 Light register set or static configuration
    • Evenly spread offset and drift correction (offset might be set hard in case of large offsets)
    • Hard setting of time possible
    • Individual hardware only PI servo loops for offset and drift correction (PI parameters individually configurable)
    • Runtime changeable PI servo parameters
    • Offset correction: min 1 ns / s, max 0.5 s/s
    • Drift correction: min 1 ns / s, max 0.05 s/s
    • Conversion of fractional adjustments into even spread clock adjustments
    • Provides time for all other cores
    • Logging of correction values
    • Linux Driver (PHC)

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.
