Work closely with our diverse team members on flows to provide DFT, and DFP methodologies for industry-leading chip designs.

• I already worked with multiple teams while doing Automative SOC bring up Linux BSP team, SVE team, PPAT team, performance team etc.
• For Qultivate feature, We need the Access Policy permission for different FW like CPUCP subsys and CPU sysVM FW. We need to suggest multiple technique so that it won't violate the security policy of the system.
• While Developing some feature, when there is some different requiement in some different SOC like Monaco only wants Gold & GOLD+ CD to access MPMM feaure where Lemasn GOLD and SILVERS both need the MPMM feaure. Gone through multiple round of discussion with HW team, Linux Team, SVE team and CPU Sys SW team. Finally coming up with accurate solution like rather doing the initialization from CPU CP FW pushed the responsiblity to TZ via SYSTEM INIT LIB.

Support development of tools using C++/Python/TCL.

MLD is Library designed by Me. It is working on the top of Kernel. Via Dynamic Memory Allocation, we directly ask Kernel to allocate memory for User Application. Now User application is asking MLD Library to allocate memory for it. We don't use OOPs priciple here we user has freedom to deisgn the system. Here it will manage all the dynamically allocated memory and detect the memory leaked. Then it will free that leaked memory.

Here we achieved the goal by considering the allocated objects as graph node where there must be one root node of the graph. All the nodes must be reachable from root node. If nodes are not reachable from root node then it is called leaked objects.

We can also achieve the same using a table and reference count for each object also.

Where Smart Pointer & Shared Pointer concept is based on Class & Object i.e OOPs. Here it will allocate memory and destroy the memory via constructor and destructor whenever object will be out of scope.
