Confusion about DRC / LVS / Parasitic extraction tools

Hello,

I am trying to install Cadence verification tools in my university but I am totally lost to choose packages.

I will use GF8HP and GF8RF PDK through MOSIS.

So, I installed Assura for DRC and LVS. Assura can make parasitic extraction?

I know there is 2 packages to make extraction too, EXT and PVS.

So, I have to use EXT, ASSURA or PVS to set QRC_HOME?

PVE doesn´t exist any more?

Thanks,

Emmanuel
