Project : 2 bit AND using MOSFET
Steps i have gone through my project :
1. Firstly, i created the schematic diagram of AND gate by using PMOS, NMOS, labeling and annotating  components respectively in esim software.
2. After designing schematic representation diagram i have checked for errors by running ERC(error rule check).
3. Once there was no error in schematic diagram ,created spice netlist so that .cir file gets created.
4. When .cir file is created i have managed to convert esim modles to sky130 models.
5. After converting into sky130 models , sky libraries are uploaded to the project folder .
6. The project file is now ready .cir file (circuit file ) is executed in ngspice simulation window.
7. Tfter simulating i have checked for the waveforms which i was submitted in the report. the waveforms were similiar.

problems faced by me in entire process:
1. Uploading sky130 lib files to the designated path was difficult.
2.  Designing schematic diagram and annotating them was a bit lengthier task.
3. Some errors were caused during the ERC but this was resolved when i went  throufh the 10 bit DAC course which was given in webinar.
well, there was some confusion on the sky130 libraries , but by the instanteneous help provided by the mentors i got to clear all the doubts from slack meeting.
 THANK YOU.
