|
* Emulators are useful tools
|
|
|
|
|
- PC emulator (e.g. Docker on Mac, WSL on Linux)
|
|
|
|
|
- NES emulator -- fun and games, realtime output
|
|
|
|
|
- Also have debugging emulators
|
|
|
|
|
- Renode
|
|
|
|
|
|
|
|
|
|
* Renode Stack
|
|
|
|
|
- CPU cores written in C
|
|
|
|
|
- arm, i386, ppc, riscv, sparc, xtensa
|
|
|
|
|
- Windows, Mac, Linux
|
|
|
|
|
- Peripherals and UI written in C#
|
|
|
|
|
- Extensible via Python and C#
|
|
|
|
|
- Write once. Run anywhere. Using C# to define new peripherals
|
|
|
|
|
|
|
|
|
|
* Three major users
|
|
|
|
|
- Designers of new boards
|
|
|
|
|
- Reverse engineering exsisting hardware
|
|
|
|
|
- Silicon designers
|
|
|
|
|
|
|
|
|
|
* Designers of new boards
|
|
|
|
|
- One or more chips
|
|
|
|
|
- How are they connected?
|
|
|
|
|
- What weird hardware exists?
|
|
|
|
|
|
|
|
|
|
* Concurrent emulation of multiple devices
|
|
|
|
|
- Can connect multiple devices, e.g. via UART, GPIO, SPI, Ethernet, CAN...
|
|
|
|
|
- All devices are emulated using the same time source
|
|
|
|
|
- Helps to debug timing differences with different processors on a board
|
|
|
|
|
|
|
|
|
|
* Board definition format
|
|
|
|
|
- Easily define memory layout
|
|
|
|
|
- Easily move blocks around
|
|
|
|
|
- Only define what's necessary
|
|
|
|
|
- You don't need to be perfect, just good enough!
|
|
|
|
|
|
|
|
|
|
* Can read SVD files
|
|
|
|
|
|
|
|
|
|
* Hardware has Similarities
|
|
|
|
|
- Picture of existing register sets
|
|
|
|
|
- There are only so many combinations
|
|
|
|
|
- Rip. Mix. Burn. Many chips are just copies of one another.
|
|
|
|
|
|
|
|
|
|
* Tests in CI
|
|
|
|
|
|
|
|
|
|
* Reverse engineering existing hardware
|
|
|
|
|
|
|
|
|
|
* If it's a supported architecture, it's easy to run code
|
|
|
|
|
* LoadBinary and set PC
|
|
|
|
|
* Can skip much of the boot ROM
|
|
|
|
|
* Attach GDB
|
|
|
|
|
* Reproducible makes it easy to test theories
|
|
|
|
|
|
|
|
|
|
* Developing new Silicon blocks
|
|
|
|
|
|
|
|
|
|
* Betrusted hardware
|
|
|
|
|
- Create a new design in LiteX / Verilog
|
|
|
|
|
- Document the design
|
|
|
|
|
- Create a model
|
|
|
|
|
- Timing isn't as critical
|
|
