I have  designed a NOR gate using CMOS in skywater130nm technology circuit
first I  designed a NOR gate using CMOS circuit in esim software but in starting my circuit is showing error in simulation time and waveform are also showing error because I have not connecd  resistor. Then I connect the resistors in parallel to pulse in inputs A and B, then also another resistor are also connecting in output. 
Now again I converted kicad to ngspice and provide the same value  as given above this time waveform comes right but in negative direction. 
Then, I changed the value of source details and transient analysis  atleast two three times to get the output waveform in positive direction.

Now I got a correct waveform in esim environment 
Then, I download sky130nm file from github and after downloaded I created a new folder on my desktop with name NOR GATE 130nm  and copy the extracted folder of 
sky_fd_pr folder from zip file and then , after all files copying of it I go to cdrive , FOSSEE , esim, NOR Gate and open the folder of NOR gate and open the 
.cir.out file into notepad first then, copy this file and paste it into that folder where there is that  sky_fd_pr folder and copy here, the .cir.out file of 
NOR gate and converted it into .cir file that is I save it as .cir file and then, open this file into notepad after that I converted all the components specifications
 into 130nm from 180nm in this file . The components of which I have converted into 130nm are nmos, pmos, resistor and then, also set the plot  according to the given 
specification of 130nm technology .

 After setting all these specifications I saved this notepad and for running this file with ngspice To Run the circuit using ngspice:
 Step 1. Right click on .cir file. 
 Step2. Click on Open With
 Step 3. Browse for the ngspice.
 Step4. Since, ngspice not present then I  scroll down and click on More Apps.
 Steps5. Go to the FOSSEE folder search for Ngspice. Run it  

After running into ngspice the graph comes but its take some time and after sometime when graph come then it show error in the ngspice. 
what error it shows is that there are
 
too few parameters for subcircuit type “sky130_fd_pr_pfet_01v8” (instance: xxm1) 
too few parameters for subcircuit type “sky130_fd_pr_pfet_01v8” (instance: xxm2)
 
then I search for this error on the Google and find about it so I came to know that I had deleted some file in the Notepad while changing specification according to 
130 nm after changing again the specifications in the Notepad of .cir file according to nmos and  pmos and resistor I again save . cir file and re run it into 
ngspice using the same process as stated above. This time, the waveform comes for individual inputs and output and I observe the graph according to truth table of 
NOR Gate then, I find that the waveform comes correct of NOR Gate using SKY130nm Technology . I got the proper output waveform for it .
After then running NOR.cir notepad in ngspice and comes all waveforms input-output. Then, I merge all waveform accordingly from input to output in paint. 
After that I also merge combined waveform input-output below it and again run ngspice by changing the plot specification in notepad of .cir file.
