I am getting error related to 
timestamp mismatch
as shown in screenshot while importing spice netlist to generate parametric layout of devices in magic. Please help to identify source of this error and how resolve it ? Device layouts not visible inside magic only pins are.
t
It appears that you did not save the parameterized device layouts after creating them.
v
Can you please share what is meant by "save the parameterized device layouts". I was following steps in following video

Generated spice netlist from xschem and imported it in magic. Is there any other steps in between ?
t
@vks: At 11515 in the video, I select "Save all and quit", which should have written all of the cells including the generated ones. The "writeall" command does the same thing. After writing, you should have multiple ".mag" files for the parameterized devices and one for the top level layout.

I am getting this issue right at beginning of layout process in magic while trying to import spice netlist to generate device pcells inside blank magic sheet. I have been able to do this step successfully in past but facing this issue now for first time.
@Tim Edwards please check attached video of error facing in magic

Can you share what's in the file 
opamp.spice
?
@vks: Actually, I think I've seen this problem before, and it comes from having files left over from a previous layout. I think there is an existing 
opamp.mag
file which is interfering with creating a new one (I will make a note that the SPICE read-in script needs to be checking for existing interfering file names).
v
Attaching required spice file. Please suggest how to resolve this issue to go ahead with layout.
opamp.spice
t
@vks: I read in this netlist without any trouble at all. Please see my comment above. Make sure there are no existing .mag files when you do the import.
v
Thanks @Tim Edwards. After deleting existing 
opamp.mag
file and re-importing 
opamp.spice
netlist successfully generated device pcells in magic
