    1)Using VHDL and the Xilinx Vivado Tools, design and implement a 4-bit ALU whose functionality is compliant with the TTL MSI 74LS381A specifications. The design must use a VHDL behavioral modeling coding style and can include concurrent and sequential statement types. Source code modules must include liberal commenting to clarify and explain function and operation your code. 2) Create a test bench VHDL module and use the Vivado Simulator to test/verify proper operation of the ALU’s functions with all input data patterns specified in the 74LS381A functional table. Recommendation: to make comparison of simulated results to those listed in the functional table easier, apply the external stimulus input patterns in the same “row” order as inputs are listed in the...

Also, it's not on the schematic, but it needs a NRF24L01 transmitter mounted directly on the PCB with antenna on the circuit board. All components on the board have to be chosen in order to make the energy saving more effective, not being able to place LEDs that can increase energy expenditure. As it is a prototype, in place of the atmega chip it needs to have a socket that holds it so that it can be remov...

    We have recently had a PCB designed to operate with BQ34Z100PW-G1 for gauge and BQ24170RGYR as our battery charging circuit controller. The circuit does not seem to be functioning with the code we currently have. We have tried a couple different solutions but realize we are in need of someone who is familiar with both parts, hardware and software designs. We can provide the circuit and all of the specific information needed to view where we are with the design. We would be able to share the current code we have for the devices, as well as we have the ability to help with debugging and trouble-shooting the physical circuit if needed.
