Simics Question:

Simics require low level access to the networking to share is resources between the host and guest system. It requires port forwarding to be used to transfer the packets. It provides a simulation of the host Ethernet’s interface to send and receive the data packets. As, operating system doesn't allow the use of simulator for Ethernet interfaces, network has to be manually configured to be used. There are two ways it can be configured.
1. Use of openif that allows the access to the simulated host Ethernet’s interface.
2. Use of TAP or virtual Ethernet this allows permissions to be set for each user for the accessing and transferring of the files.
