2 SimicsĀ® RISC-V* Simple Overview

The RISC-V* Simple virtual platform is a RISC-V-based system that contains one or more processor cores along with the basic peripheral devices needed to boot a Linux kernel. The system is not intended as a virtual platform corresponding to a real RISC-V-based board, but rather to allow software development and test on a generic configurable platform similar to other virtual-only models used in the RISC-V ecosystem.

The virtual platform contains RISC-V processor cores (defaulting to RV64GCB), RISC-V interrupt controllers (CLINT and PLIC), a serial port (UART, NS16550), virtio block devices to hold filesystems, a virtio Ethernet device, and a virtio entropy device (hardware random number generator).

All models in the system can be inspected using the .info and .status commands on the objects.

0x10020000 0x10000 board.disk0 Virtio disk 0
0x10030000 0x10000 board.disk1 Virtio disk 1
0x10040000 0x10000 board.disk2 Virtio disk 2
0x10080000 0x10000 board.virtio_entropy Virtio entropy device
0x80000000 0x80000000 board.ram RAM (size is configurable)

The command memory-map shows the memory layout of the system.

Some devices are modeled with limited functionality. See chapter 6 for more information about these limitations.
