A testbench is simply a HDL module that instantiates the module you want to test and provides input stimulus. It's just another .vhd or .v file. Xilinx ISE can generate the basic skeleton for you. Maybe Quartus can as well.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
