@Tim Edwards Do you have any idea on how to use the rram layer in commercial pdk of sky130 ? We have an rram layer in sky130B in opensource pdk but there is no rram layer in the commercial pdk. Any way I can use it ?

Once @Tim Edwards told me that the ReRAM does not exist in original (commercial) Sky130 process and it is an extension by MIT. Tim, am I right?

@Tim Edwards @manili @Talha Bin Azmat If we Can create the same pre-made RRAM available in the open pdk in the commercial PDK in Cadence Virtuous, it will be awesome. For that we need to know what is the r1c layer and its corresponding layer in the commercial pdk? If this is the case: In Virtuous, some files need to be amended so it can pass the LVS and run Pex. And this can be done easily I think! For the LVS, we can amend the “calibre.lvs” to generate an equivalent matched circuits. For PEX: we can amend “calibre.rcx” files to generate extracted view with all the parasitics Additionally, the the commercial design kit contains another file named “source.added”. This file contains the information of all the sub circuits in the design kit. And this one can be amended.
