  • 電子書-RTL Design Style Guide for Verilog HDL540頁

    電子書-RTL Design Style Guide for Verilog HDL540頁A FF having a fixed input value is generated from the description in the upper portion of Example 2-21. In this case, ’0’ is output when the reset signal is asynchronously input, and ’1’ is output when the START signal rises. Therefore, the FF data input is fixed at the power supply, since the typical value ’1’ is output following the rise of the START signal. When FF input values are fixed, the fixed inputs become untestable and the fault detection rate drops. When implementing a scan design and converting to a scan FF, the scan may not be executed properl not be executed properly, so such descriptions , so such descriptions are not are not recommended. recommended.[1] As in the lower part of Example 2-21, be sure to construct a synchronous type of circuit and ensure that the clock signal is input to the clock pin of the FF. Other than the sample shown in Example 2-21, there are situations where for certain control signals, those that had been switched due to the conditions of an external input will no longer need to be switched, leaving only a FF. If logic exists in a lower level and a fixed value is input from an upper level, the input value of the FF may also end up being fixed as the result of optimization with logic synthesis tools. In a situation like this, while perhaps difficult to completely eliminate, the problem should be avoided as much as possible.

  • 一種低成本高可靠的SFP+光收發(fā)模塊電路研究與實(shí)現(xiàn)

    本文首次設(shè)計(jì)并驗(yàn)證了基于macom三合一芯片設(shè)計(jì)的光模塊電路,該電路旨在提供一種滿足SFF-8472中規(guī)定的數(shù)字診斷功能的低成本SFP+模塊。電路采用激光器驅(qū)動、限幅放大器、控制器以及時鐘恢復(fù)單元集成的單芯片,在保證高精度數(shù)字診斷功能基礎(chǔ)上,實(shí)現(xiàn)了低成本高可靠的特點(diǎn)。該電路在光接收接口組件與激光器驅(qū)動和限幅放大器單元的限幅放大器部分之間接入濾波器來提高模塊的靈敏度及信號質(zhì)量。在控制器單元的數(shù)字電位器的引腳上采用外加電阻的方式避免出現(xiàn)上電不發(fā)光的故障問題。該研究結(jié)果為下一代SFP-DD光模塊設(shè)計(jì)與開發(fā)工作,奠定了一定的理論與實(shí)踐基礎(chǔ)。This paper designs and validates the optical module circuit based on the MACOM Trinity chip for the first time.This circuit aims to provide a low-cost SFP module which meets the digital diagnosis function specified in SFF-8472.The circuit uses a single chip integrated with laser driver,limiting amplifier,controller and clock recovery unit.On the basis of ensuring high precision digital diagnosis function,it achieves the characteristics of low cost and high reliability.The circuit connects a filter between the optical receiving interface module and the limiting amplifier part of the laser driver and limiting amplifier unit to improve the sensitivity and signal quality of the module.The pin of the digital potentiometer in the controller unit is equipped with an external resistance to avoid the problem of power failure.The research results lay a theoretical and practical foundation for optical module design in high-speed data center.
