The user can switch between configurations at startup by specifying the required configuration file with the -f option. If no configuration file is specified or1ksim searches for the default configuration file sim.cfg. First it searches for './sim.cfg'. If this file is not found, it searches for '~/or1k/sim.cfg'. If this file is not found too, it reverts to the built-in default configuration. NOTE: Users should not rely on the built-in configuration, since the default configuration may differ between version. Rather create a configuration file that sets all critical values. This file may contain (standard C) comments only - no // support. Configure files may be be included, using: include "file_name_to_include" Like normal configuration files, the included file is divided into sections. Each section is described in detail also. Some section have subsections. One example of such a subsection is: device instance specific parameters... enddevice which creates a device instance. */ /* MEMORY SECTION This section specifies how the memory is generated and the blocks it consists of. type = random/unknown/pattern Specifies the initial memory values.
