@Rafeeq Khan Mohammed you need to: • download

openvaf

• execute

openvaf <http://sky130_fd_pr_reram__reram_module.va|sky130_fd_pr_reram__reram_module.va>

• put the resulting

sky130_fd_pr_reram__reram_module.osdi

file into

....../share/pdk/sky130B/libs.tech/ngspice

• then create an empty directory • put the

....../share/pdk/sky130B/libs.tech/xschem/xschemrc

file into it. • Open a terminal in this directory • In the terminal type:

export PDK=sky130B

• run xschem:

xschem sky130_tests/tb_reram.sch

• Press

Netlist

button • Press

Simulate

button • Go to menu button

Waves ->Tran

to load the waveforms The

tb_reram.sch

is a testbench that uses the reram cell. You can see how the reram is used so you can draw your own circuits.

I compile

.osdi

file from

<http://sky130_fd_pr_reram__reram_module.va|sky130_fd_pr_reram__reram_module.va>

with openvaf and in one machine and then transfer the

.osdi

file in to another machine where I have ngspice installed, and followed the steps, but pressing simulation button, it shows thats there is no osdi file available. Could anyone please help.

@Hridi Prova Debnath I think check the version of ngspice is it compatible with osdi if not update ngspice and try
