Pcb design assignmentI need help to design a 5v power supply on Proteus. Please note that the professor was specific and so the design must be done on Proteus.You don’t have to include the transformer but you can use header pins to represent it. Also, please include an LED on the output side and also use header pins to represent the output. About the voltage regulator, I’d prefer it if you used the LM7805 but you can use any other if it will make the design simple.This is group work. We are Group 1. The name ‘Group One’ along width ‘Power Supply’ must appear on the PCB.Let me know if you need anything else.Thank you so much

Lab07: Advanced Binary instrumentation with pin
Using PIN for vulnerability detection
Lab Description: In this lab you will modify an existing pintool to detect various dynamic memory allocation errors. This class of programming errors often results in exploitable vulnerabilities.
______________________________________________________
LAB EXERCISE: DETECTING DYNAMIC MEMORY ALLOCATION ERRORS WITH PIN
Background : There are a number of common programming errors associated with dynamic memory allocation / deallocation (using malloc() and free() in C). We’ll concentrate on two, specifically double free and use after free.
A double free error occurs when a single allocation obtained via a malloc() call is free()-ed twice. A double free error and an illustration of the corresponding heap corruption (in which two allocations becomes aliased and point to the same block of storage) are presented in the figure below:
A use-after-free error occurs when an allocation obtained via malloc() is free()-ed and then subsequently used again. This almost always results in heap corruption and is often exploitable. A use-after-free error and an illustration of the corresponding heap corruption are presented in the figure below:
Your Task
In lecture, we will developed a pintool that could analyze malloc() / free() calls in a target application, displaying information about arguments and return values. The pintool is called mallocfreev3.cpp. Modify the pintool to track the allocations obtained via malloc() and deallocated via free() and discover both use-after-free and double free errors. Diagnostic information should be generated which will guide the correction of the errors. You should demonstrate the correctness of your pintool by generating a number of test cases, based on the use-after-free and double free examples illustrated in the figures.
What to submit
Submit a copy of the source code for your pintool and test cases for this lab on Blackboard.
