What is AMS Modelling?
Verilog-AMS is an industry standard modeling language for mixed signal circuits. It provides both continuous-time and event-driven modeling semantics, and so is suitable for analog, digital, and mixed analog/digital circuits.
Is Verilog the same as SystemVerilog?
The main difference between Verilog and SystemVerilog is that Verilog is a Hardware Description Language, while SystemVerilog is a Hardware Description and Hardware Verification Language based on Verilog. In brief, SystemVerilog is an enhanced version of Verilog with additional features.
What is a Verilog simulator?
Verilog is a hardware description language and there is no requirement for designers to simulate their RTL designs to be able to convert them into logic gates. Simulation allows us to view the timing diagram of related signals to understand how the design description in Verilog actually behaves. …
How to model analog and digital in Verilog-AMS?
In verilog-AMS views, you can model digital and analog behaviour together in the same module e.g. you might need to define control registers (digital) in your block. When using verilog-AMS models, you will have to use ‘ams’ as the simulator.
What is cadence Verilog-AMS?
This manual describes the analog and mixed-signal aspects of the Cadence®Verilog®-AMS language. With Verilog-AMS, you can create and use modules that describe the high-level behavior and structure of analog, digital, and mixed-signal components and systems.
What are real behavioral models in Verilog?
Real Behavioral Models in Verilog Real variables can model analog currents and voltages in discrete time with accuracy approach- ing that of analog simulators[1][2]. In fact, analog simulators only evaluate at discrete time steps as well, so the difference between the two approaches is less than it appears.
What is the difference between AMS and Spectre?
Using ‘ams’ as the simulator means that the digital content of your models will be solved by an event-driven digital kernel in the ams simulator, while the analog part will still be solved by Spectre/APS, however this version of Spectre will be used from Incisive/Xcelium.
