Hi prabhu, You have not made it clear if your question is for (1) a simulation or (2) just a circuit diagram. If (1) then there are several ways you can edit component values quickly. You can: a) draw the circuit in EasyEDA then export the spice netlist of the circuit and edit it in any text editor and then paste the netlist back into a new schematic and run it directly as a netlist. To export the spice netlist do: **Green Man > Simulation Results... > Download netlist** then click in the netlist text and then do Ctrl+A and Ctrl+C to copy the netlist. Then Ctrl+V to paste it into your favourite text editor. or: b) If you understand the spice syntax, you can write the netlist by hand in a text editor and then paste it into an EasyEDA schematic sheet and run it. To paste and run a spice netlist in EasyEDA, see: or: c) Draw the schematic in EasyEDA and use parameters to set the capacitor values: See: or: d) Draw the schematic in EasyEDA and then edit the EasyEDA Source file: **Document > EasyEDA Source** and follow the instructions in the window that opens. To understand the EasyEDA Source syntax please see: If (2) then you can draw the schematic in EasyEDA and then edit the EasyEDA Source file: **Document > EasyEDA Source** and follow the instructions in the window that opens.
