SKKU Spike RISC-V ISA Simulator assignment

About

Spike, the RISC-V ISA Simulator, implements a functional model of one or more RISC-V harts.

Build Steps

 $ apt-get install device-tree-compiler
 $ cd Spike_Assignment
 $ mkdir build
 $ cd build
 $ ../spike/configure
 $ make
 $ [sudo] make install

Running a Simple C Program

Now you can simulate the program atop the proxy kernel:

$ cd ..
$ ./build/spike ./pk/pk bench/test1

Interactive Debug Mode

To invoke interactive debug mode, launch spike with -d:

$ spike -d pk hello

To see the contents of an integer register (0 is for core 0):

: reg 0 a0

To see the contents of a floating point register:

: fregs 0 ft0

or:

: fregd 0 ft0

depending upon whether you wish to print the register as single- or double-precision.

To see the contents of a memory location (physical address in hex):

: mem 2020

To see the contents of memory with a virtual address (0 for core 0):

: mem 0 2020

You can advance by one instruction by pressing the enter key. You can also execute until a desired equality is reached:

: until pc 0 2020                   (stop when pc=2020)
: until reg 0 mie a                 (stop when register mie=0xa)
: until mem 2020 50a9907311096993   (stop when mem[2020]=50a9907311096993)

Alternatively, you can execute as long as an equality is true:

: while mem 2020 50a9907311096993

You can continue execution indefinitely by:

: r

At any point during execution (even without -d), you can enter the interactive debug mode with <control>-<c>.

To end the simulation from the debug prompt, press <control>-<c> or:

: q
