In this course, you focus on Real-Number Modeling (RNM) using the SystemVerilog language in a mixed approach, borrowing concepts from the digital and analog domains to enable high-performance, digital-centric, mixed-signal verification. In the course, you learn how to model analog block operatio...
and RF mixers. Modules 19-20 add modeling support concepts including sampling methods and instrumenting analog measurements. Modules 21-24 focus on verification including the use of SV assertions, real randomization, real coverage, and managing model abstractions. Modules 25-27 describe advanced concept...
A Phase Locked Loop (PLL) model is considered as a vehicle to demonstrate the different proposed techniques. It is shown that using a pure System Verilog model, it is possible to achieve a comparable accuracy to Spice transistor-level simulation with a 27x simulation speedup.Mina Louis...
A SystemVerilog-based real number model for a Voltage-Controlled Oscillator (VCO) is proposed, in order to enhance simulation performance. The presented model is compared to a Verilog-AMS based VCO model. The simulation runs took place in Cadence Virtuoso - AMS Simulator (for the Verilog-AMS ...
;在图8.3-1中,信号发生器Generator产生不同输入激励送到驱动模块Driver中,接口Interface包含了所有的设计端口信号,用于驱动和监控;驱动Driver将产生的激励信号通过Interface送给被测电路;监视器Monitor通过监控被测电路DUT的输入/输出信号,从而捕获电路行为;计分板ScoreBoard包含参考模型ReferenceModel和比较逻辑ComparisionLogic...
Monitor的主要功能用来观察DUT的边界信号或者内部信号(尽量少),并且结果打包整理传送给其他验证平台的组件(Checker比较器)。 Checker负责模拟设计行为和功能检查的任务,将DUT输入接口数据汇集给内置的reference model(参考模型),通过数据比较检查DUT功能。 2.3 任务和函数 函数function: 不会消耗仿真时间,无法调用task,可以...

A packed union allows data to be written using one format and read back using a different format. The design model does not need to do any special processing to keep track of how data was stored. This is because the data in a packed union will always be stored using the same number of...
