Advanced introduction to digital IC Design SOC

Statement ： This series of articles are all from the collection of online public materials , And attach a link to the web page at the end of the article . Only for learning and communication , Not for commercial use .

Preface

Master's degree, engaged in FPGA Logic development has N year , For the future development direction 、 Technology upgrading is full of confusion 、 confused . here , Coincide with figures IC The rise of design Posts , Also successfully transferred offer, This is also doomed to the hard life of drifting North in the next few decades .

Only record your learning and growth in this article , I hope I can continuously improve my professional skills , Also for other readers to understand SOC Provide reference in the field of work .

This article continues to be more in .

3、 ... and 、 Career prospects  

Whether taking the technical route or the management route , In the first six years of work, I mainly focused on technical improvement , There's not much difference . The rank promotion is as follows ：

Master's degree 0~3 year （ Corresponding undergraduate 0~5 year ）：level 1

Master's degree 3~6 year （ Corresponding undergraduate 5~8 year ）：level 2

Master's degree 6+ year （ Corresponding undergraduate 8+ year ）：level 3

Rising to level 3 In the future, you have to consider your career development direction . from level3~level4 In fact, it's hard to say how many years it will take , Some people may need 3 year , Some people need five years , It depends on ability and opportunity , Most people arrive level4 There should be no problem . At this time, the salary basically reached the bottleneck of a technician （65-80W）

and level 5, even to the extent that Fellow and Director And above , It belongs to a small number of people . Or it's a big player in the industry , Those who have made outstanding contributions to the company , Or the headhunter's favorite , Executives who push glasses and change lamps on the wine table .

Level 5 It can be said to be a threshold for an annual salary of one million .

From the perspective of the development prospects of the two positions ,level 4 It was basically the same before , Go up and break through , Design should be more advantageous . It's easier to change from design to architecture and manager .

notes ： The above is just a personal opinion , Not absolutely .

Four 、 Job content

IC The main responsibilities of the design are as follows :

• Make design scheme according to function , To develop Microarchitecture , Prepare detailed technical documents .
• Use Verilog Conduct RTL logic design , Realize module functions .
• Carry out logical synthesis 、 Timing analysis , Complete timing convergence .
• Small and medium-sized chips may also participate in DFT The job of .
• Participate in chip system debugging , Post simulation 、FPGA Verification, etc .

IC The main responsibilities of verification are as follows ：

• read design spec, To write verification spec, To develop test plan.
• Build a verification environment (C/C++,systemC,systemverilog）.
• establish test cases.
• monitoring regression And promotion coverage
• support Other engineers .
