Linux Terminal Steps: Username: student01 Password: student01

1. Open Terminal from Desktop i.e. Right Click in the center of plane Desktop and use “Open Terminal” 2. Start the License Server 3. Check the License Manager Status 4. Create Directory with Student USN as Directory Name 5. Inside Student USN Directory Create Workspace directory 6. Copy Library files (i.e. tsmc018_typ.syn and adk.v) from

/home/student01/libraries/ 7. Here are some Commands in Steps 1 8. Follow the below Steps 2 to execute front end programs Note: $ Linux prompt Just like C:\> MS DOS prompt Linux is Case sensitive Always use only Small Letters/Alphabets

:q Quit VI. If there have been changes made, the editor will issue a warning message. :q! Quit VI without saving changes.

:vi␢proj1.vStarts editing a new file. If changes have not been saved, the editor will give you awarning. :w Write out the current file.

:w␢proj2.v Write the buffer to the filename specified. :wq Write the buffer and quit. :wq! Write the buffer and force quit.

Steps 2: 1. Create Mainmodule Verilog

$ vi␢sync_counter.v↵ 2. Check Syntax error of Only Mainmodule Verilog

$ vlog␢sync_counter.v↵ 3. Create Testbench to test Mainmodule Verilog

$ vi␢sync_counter_testbench.v↵ 4. Check Syntax error of Only Testbench

$ vlog␢sync_counter_testbench.v↵ 5. Check compatibility of both Top/Mainmodule and Testbench together to obtain Top-module name

$ vlog␢sync_counter.v␢sync_counter_testbench.v↵ 6. Simulate Testbench in Text mode using

Top-module name in Vsim

$ vsim␢–c␢sync_counter_testbench␢–novopt↵

VSIM1> run␢-all↵ 7. Simulate Testbench in GUI/Graphical mode in Modelsim

$ vsim␢sync_counter_testbench␢–novopt↵ 8. Generate SDF and Netlist file from Spectrum using constraints provided

<leonardo 16> exit↵ 9. Create Gatelevel Testbench to test Mainmodule Verilog using 180 nm Technology

$ vi␢sync_counter_gatetestbench.v↵ 10. Check Syntax error of Only Gatelevel Testbench

$ vlog␢sync_counter_gatetestbench.v↵ 11. Check compatibility of Netlistfile, Gatelevel Testbench and adk.v library together to obtain Top-module name w.r.t. 180 nm

Technology

$ vlog␢sync_counter_netlist.v␢sync_counter_gatetestbench.v␢adk.v↵ 12. Simulate Gatelevel Testbench in Text mode using

Top-module name in Vsim
