Building The Instruction-Accurate Simulator (IAS)

IAS has been extensively tested only on the Sparc/Solaris platform. It is compiled with the Sun Workshop C compiler. If you do not have access to this compiler, you can try compiling with gcc.

If you need to build IAS on a different platform, you should read the IAS Porting Notes.

For more on the build structure and details on the source code, please refer to IAS web pages.

Building IAS

A default SPARC/Solaris binary for the Instruction-accurate simulator (IAS) is supplied with the distribution in $DSVHOME/bin.

The steps to recompile IAS for your SPARCstation running Solaris are:

1. Ensure your environment variables are set. See setting up your environment.
2. Change your directory to $DSVHOME
3. Type make ias. The ias executable appears in the directory $DSVHOME/bin if everything builds correctly. (If you see warnings of the form: " warning: typedef redeclared: uint64_t", you can ignore them)

Installing trap handlers

Before you can run a program on IAS or on the RTL model, you must have all picoJava-II trap handlers present in the directory $DSVHOME/class. The picoJava-II processor distributions already contain default trap handlers in this directory. Note that these trap handlers are example implementations only, and may have to be substantially modified before being used in a real system.

If you need to modify or recompile these handlers, the source code is present in $PICOJAVAHOME/$PROJECT/design/traps (for emulation traps) and $PICOJAVAHOME/$PROJECT/design/exception (for all other traps).

The steps to build the trap handlers are:

1. cd $PICOJAVAHOME/$PROJECT/tools/traps
2. make
3. cp class/*.class $DSVHOME/class
4. cd $PICOJAVAHOME/$PROJECT/tools/exception
5. make
6. cp class/*.class $DSVHOME/class

1. cd $PICOJAVAHOME/$PROJECT/sim/test/pico_vts
2. Type steam -ias .
