DesignWare(R) ARC(R) Emulation (nsim)
#####################################

Overview
********

This board configuration will use `Designware ARC nSIM`_ to emulate a virtual
ARC EM based board including the following features:

* ARC EM processor
* ARC internal timer
* a virtual output only console (uart-nsim)

There are two sub configurations in board:

* nsim_em which includes normal em features and ARC MPUv2
* nsim_sem which includes secure em features and ARC MPUv3

For detailed arc features, please refer to
:file:`boards/arc/nsim_em/support/nsim_em.props` and
:file:`boards/arc/nsim_em/support/nsim_sem.props`.
