OVP Peripheral Model: AlteraDwApbTimer
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.
Description
Model of dw-apb-timer for CycloneV platform.
Limitations
Only functionality required for Altera Cyclone-V is implemented: single timer, 32 bits, little endian only
Resolution of this timer is limited to the simulation time slice (aka quantum) size
