# EMIR New hire training

# Welcome on board, new hires!

We provide a tree-like training plan for you.

Most of the materials are designed in <u>self-driven study</u> flavor. 

Please check below expert-tree first, and start with level-0 lectures. 

Good good study, day day up!

# Level-0 Background and environment

## On board environment setup.

* Check your environment before next step on_board_check_list.pptx

 Note: if you can't find SH printer driver, use this: Win_x64.zip or ask IT for help

* Document templates (New version after 20220815) GIGA_VI_Standards

## Refresh VLSI knowledge.

* Step 1: Go through the briefing slide EDA_BG_Briefing.pptx Make sure you are familiar with fundamental terminologies. Try to answer the questions in the slides.

(Hint 1: most of the answer in this book CMOS_VLSI.part1.rarCMOS_VLSI.part2.rar )

(Hint 2: You can use FreePDK45_Giga.rar as standard cell library, and use Ngspice to setup transistor-level circuit simulation.)  

* Step 2: Hand out your answers to tutor, you are welcomed to raise new questions to us.

* Next step: EDA_Traveller

## Get ready to survive in Linux world0 A quick start EDA journey.

* Please follow Survive_linux to learn how to survive in GIGA Linux environment.

## Useful tools {under /rnd1/jchen/newhire_training/util_scripts )

```

vp_hello	// show usage and help message

vp_newhire	// setup environments during on-board day

vp_new	        // vp—checkout + vp—make check out code from server and build AG/VP/C日T

vp_checkout     // check out latest code from gitlab server

vp_clean        // clean up binary (make clean)

vp_make         // build VP binary, or...

                      vp_make ir pow            // will make ir and pow module as debug version

                      vp_make ir VERBOSE        // will enable verbose message during compile

                      vp_make pow ta FORCE      // will call a machine and force compile, if resource is limited

ag_make	        // build AG binary, or...

	        // usage is same as vp—make

cht_make	// build CHT binary 

	        // usage is same as vp—make

rs_make	        // build RS binary

vp_sync/ag_sync/cht_sync	// get latest code from server, and refresh ctags

vp_sync_force   // 髻 强伲merge conflict叩叩且叩正叩交叩 

vp_regression   // run VP regression suite under your client (M-ST do for functional check-in flow)

cht_regression  // run C日T regression suite

ag_regression   // run AG regression suite under your client (M-ST do for functional check-in flow)

ag—regression clean  髻 cleanup local regression data, same as "vp—regression clean" 

vp—commit	//print check-in flow guidance

vp—push	        // perform sync-up, AG/C日T/VP build, run simple check, and push your code to gitlab server

vp—revert	// a simple guidance if you want to give-up change, or solve conflict... 

ut—push	        // push changes for ut case, will do --rebase

VP—cut—build	// how to build cut release to AF  (commit id in etc/ci—log)

```

Note: If vp_sync or git pull failed with "You are not currently on a branch" try to use git checkout hongtu to recover branch info.
