Let us see how to run the SPEC95 benchmarks (little endian) namely compress95, anagram, go, cc1 and perl in Simplescalar simulator software. Each and every benchmark has a corresponding input file that specifies the input to the program and an output file which we can use to verify if our test was successful. Also we will be writing the output of our simulation to a file with a .out extension and we will be printing the execution trace with all the run statistics to a file with a .trace extension.

The little endian version of the benchmarks and the input and output files can be download from the below location. After extracting the archive,  place the folder BenchMarks_Little in the simplesim-3.0 folder of your simplescalar installation folder. All the benchmarks shall be executed from the simplesim-3.0 directory.

The below command will execute the compress95 benchmark and print the output to compress95.out and log the execution trace to compress95.trace in the Results folder

./sim-outorder BenchMarks_Little/Programs/compress95.ss < BenchMarks_Little/Input/compress95.in  2> BenchMarks_Little/Results/compress95.trace > BenchMarks_Little/Results/compress95.out

The below command will execute the go benchmark and print the output to go.out and log the execution trace to go.trace in the Results folder

./sim-outorder BenchMarks_Little/Programs/go.ss 50 9 BenchMarks_Little/Input/2stone9.in  2> BenchMarks_Little/Results/go.trace > BenchMarks_Little/Results/go.out

Before executing the anagram program place the words file from the Input folder in the simplesim-3.0 directory. The below command will execute the anagram benchmark and print the output to anagram.out and log the execution trace to anagram.trace in the Results folder

./sim-outorder BenchMarks_Little/Programs/anagram.ss words < BenchMarks_Little/Input/anagram.in  2> BenchMarks_Little/Results/anagram.trace > BenchMarks_Little/Results/anagram.out

The below command will execute the cc1 benchmark and print the output to 1stmt.s in the Programs folder and log the execution trace to cc1.trace in the Results folder

./sim-outorder BenchMarks_Little/Programs/cc1.ss -O BenchMarks_Little/Input/1stmt.i 2> BenchMarks_Little/Results/cc1.trace

Before executing the perl program place the perl-tests.pl file from the Input folder in the simplesim-3.0 directory. The below command will execute the perl benchmark and print the output to perl.out and log the execution trace to perl.trace in the Results folder

./sim-outorder BenchMarks_Little/Programs/perl.ss < perl-tests.pl 2> BenchMarks_Little/Results/perl.trace > BenchMarks_Little/Results/perl.out
