Lets write some code module fork_test; initial begin for (int j=0; j<3; j++) begin fork $display(j); join_none end end endmodule Output 3 3 3 It outputs 3 because there is only one variable j shared by all the threads, and its value is 3 before any of the threads start executing. None of the
How do we move from given specification to sign off for hardware Logic designer writes the specification for given design. Verification engineer goes through the specification provided by logic designer. He/She makes verification plan for the given specification of the logic design. Next step is to develop testbench. After developing testbench , it has to
Embedded is something which revolves around how to use an IC, where all the specs and properties and per defined and you cannot modify it. You have to just use IC as per your need. VLSI is something revolves around how to create an IC. Here you are the one who describe the functionality of IC. Even
Well computer architecture can be learned by following sites 1 Coursera , a course from priceton university by David Wentzlaff , you can enroll for course. link( : https://www.coursera.org/learn/comparch), click 2 NPTEL , a course from IIT Delhi by Dr. Smruti R. Sarangi , you can access his contents freely link (: https://onlinecourses.nptel.ac.in/noc18_cs29/preview) click 3. Youtube, a
To become expert in formal domain verification engineer need to know. Let’s go one by one A person who comes from simulation background , he or she knows, how check is written for a given logic design. Something similar happens in formal verification as well, he or she need to understand how do we write
In formal verification there are three type of proof 1. The property is passed it means that the property is unreachable 2. The properties failed, it means the design is not behaving correctly. 3. The properties unsolved, it will it ran for many hours, result is non conclusive. When we talk about unsolved what does
There are many formal app which has been developed for different purpose Formal property verification app: It is used for verify the property of any logic. 1.Block level or end-to-end properties 2 interactive debug what if and constraint setting 3 high performance and capacity Sequential Equivalence Check APP : It is used to verify equivalence check
Verification is process of ensuring specifications/features of hardware are matched as per the intend. So to ensure verification of chip, there are many level of verification are done Like, IP verification subsystem verification Full System Verification and to do verification there are few methodologies are available like 1 SIMULATION 2 EMULATION 3 FPGA prototype In
Risc V is open architecture for microprocessor originally developed by University of California, Berkeley. Now there are 100 members who are researching on RISC V and making many more stuff for this architecture. Members comprises of Bluespec, Inc.; Google; Microsemi; NVIDIA; NXP; University of California, Berkeley; and Western Digital, more Every year RISCV foundation host global events/conference
