VLSI Engineers working in other areas (such as FPGA, STA, Design, etc), and willing to broaden their skills and explore opportunities to further grow up their career. TESTING TESTCASE 1 -- Basic Transaction with 14 data's and no parity and 1 stopbit, no stick and no break, 8 bits in the character TESTCASE 2 -- Changing the number of bits in the character among 5,6,7,8 5. Written natively in System Verilog or the e language for optimum performance, all of our VIP components are OVM/UVM or eRM compliant and can be provided as source code under our Flexible. - Assertion-Based Verification using SVA and PSL languages. Must have good exposure to IP or SoC level verification. In order to use the uvm_object methods ( copy, compare, pack, unpack, record, print, and etc ), it connects the DUT and Verification environment components. In SoCs, the clock control unit is critical, and this is not a standard IP. UVM provides the backdoor access sub-routines for force/release or read/deposit some vale on any hierarchical path provided in the argument. The article focuses mostly. 6 of I2C specifications from Philips. 0) has a feature which can connect the DUT with the generated UVM Testbench and it also can generate a simulation file for Cadence IUS. Worked on Memory controller verification like; RLDRAM,QDRIV,DDR4,LPDDR4, NVDIMM Interested in SoC development and verification projects. , only writing data to an address can be done. An Introduction to Functional Verification of I2C Protocol using UVM @inproceedings{Yun2015AnIT, title={An Introduction to Functional Verification of I2C Protocol using UVM}, author={Young-Nam Yun and Jae-Beom Kim and J. Typically, the buses that are checked are external buses and may be industry standard buses such as PCI, DDR, I2C or proprietary buses. Using verification plan, SystemVerilog verification | |environment for this code has been developed and verified different test | |cases attaining good code and functional coverage. Download Citation on ResearchGate | On Jul 18, 2015, Deepa Kaith and others published An Introduction to Functional Verification of I2C Protocol using UVM. I can then. This advanced course on ASIC Verification with 100% placement assistance offers the high-class training on latest verification skills i. they verify the all functions of GPIO core by writing verification code in UVM (Universal Verification. A look at the challenge of Ethernet verification as data rates rise and the standard is applied in a wider variety of applications. Title: An Introduction to Functional Verification of I2C Protocol using UVM: Authors: Kaith, Deepa; B. It seems from me you're talking about generating the stimuli. Use assertion based verification to verify module or SOC level. Main activities Chip Level test plan and Verification of TROM chip using UVM Architecture. Verification of CHIP main interface involving I2C, SPI, APB & AHB bridges (UVM/SystemVerilog). 0 VIP –DVB-H/T Control Platform delivered as hard macro –General Purpose 8 bit Microcontroller SOC –Hearing aid control chip digital design and verification –Conditional Access Processor for Set-top box applications. • Good knowledge of Verification using constrained random stimulus & directed testing along with functional coverage, code coverage and, assertion-based verification methodologies in fulfilling the Verification plan requirements. There are four (4) general-purpose clocks (100MHz, 200MHz, 300MHz, and 400MHz) available to the FPGA, three (3) dedicated clock oscillators with buffers for the QDR-II memory, a dedicated clock generator for the PCIe interface, and up to two (2) i2c programmable oscillators for the QSFP28 interfaces. • Layer PSS effectively into existing UVM and SoC testbenches, use sequence generation based on abstract scenario models from non-verification engineers • Effective methods to reuse IP simulation test scenarios within system level tests without rewriting, to drive SoC emulation apost-silicon verificationnd. pdf), Text File (. In this project, from a design perspective, the master is a hardware block, and the slave is a verification IP. ASIC verification engineer with 10 yrs experience. The Veloce Transactor Library is a family of accelerated Verification IP that speeds verification by several 1000x when using standard simulation testbenches, such as UVM and SystemC. In first phase uvm components are introduced. The paper describes how the verification of an I2C system uses the powerful tools of UVM. methodology integration issues to consider ? > System Level Verification Environment ? You could probably have different ideas than above questions. • Strong and consistent hands on experience in verification of block/subsystem/Chip for various SOCs & Asics. Role is to develop the verification environment using UVM, write the test plan, create the test cases, coverage reports and integrate VIP with RTL for following protocols SPI,I2C,AXI Role is to develop the verification environment using UVM, write the test plan, create the test cases, coverage reports and integrate VIP with RTL for following protocols SPI,I2C,AXI. • Behavioral modeling in SystemVerilog, SVA and Python. This paper contrasts the reusability of I2C using UVM and introduces how the verification environment is constructed and test cases are implemented for this protocol.
