OVP Peripheral Model: SafepowerRingOscillator

Model Specific Information

This page provides introductory usage information for an Imperas OVP peripheral behavioral model. The page is split into sections providing specific information for this peripheral, including any ports for connecting into a platform, registers, other component parts, and configuration options and general information for peripheral modeling with Imperas OVP.


Ring Oscillator


Open Source Apache 2.0


This model is a register only model that returns the COUNT value from a memory location.

No behavior is currently included in the model, the COUNT register value is provided by a memory location, initialized to (2097152 = 25oC).




The ring_oscillator peripheral model is located in an Imperas/OVP installation at the VLNV: / peripheral / ring_oscillator / 1.0.
