begin the installation, as follows. To install under Windows, double-click on the self-
extracting executable. To install under Linux, extract the zipped tar file as shown below:
tar –xzf Simnow-Linux64-<version>.tar.gz
2.3 Directory Structure and Executable
After the opening screen and license agreement are displayed, you will be prompted to
choose an installation directory. When you select this, the install program will copy the
executable files and device models to the selected directory and setup the registry entries
necessary to run the simulator.
The install program will create the following subdirectories under the install directory:
analyzers
devices
doc
help
icons
images
productfile
reg
devel
tools

Under Windows each model is a Windows DLL. Under Linux each model is a Linux library. Each model has a ".bsl"
extension.
2.4 Setting up Linux for the Simulator
Make a file: "/etc/sysctl.conf" (or add to the existing one)
# This is here to make sure we get enough "mmap"able virtual address
# space, in 4K pages.
# too small.
vm.max_map_count = 1048576
# This line doesn't need to be here for newer Linux kernels, but some
# early AMD64 Linux kernels would log SEGVs even if a process had a
# handler for them, which is what SimNow does.
debug.exception-trace = 0
Then run "sysctl -p", or make sure the boot sequence does this if you don't want to run it
at each reboot.
Newer Linux distributions may set a per-process memory limit by default. SimNow
allocates a large amount of memory that is never touched. This untouched memory will
not be backed by DRAM or swap, but Linux counts it against SimNows process memory
limit when it comes to resource limits.
