The distribution includes a top level make file, which will build the target model and link it to the GDB RSP server interface. Plain make will build an unoptimized server and model. Using make run-fast will build a model with profile-based optimization (which can increase performance by a factor of 3). Using make VFLAGS=-trace will build an unoptimized version of the server and model which also generates a VCD dump of the model in v-dump.vcd (and consequently runs many times slower).

The build process assumes the availability of packages from other Embecosm packages. In particular the Embecosm Cycle Accurate SystemC interface [9] is assumed to be installed in /opt/ca-sysc-jtag and the Cycle Accurate SystemC Model generated using Verilator [10] is assumed to be in a peer directory named or1k-verilator. Alternative locations may be used by editing the top level Makefile.

A number of additional parameters are available, which mirror the parameters described in Embecosm Application Note 6, High Performance SoC Modeling with Verilator: A Tutorial for Cycle Accurate SystemC Model Creation and Optimization [10].
