    XDB Database not available Error (Cadence Virtuoso, Calibre LVS)

    I've seen this question posted in several dead threads, but never with a solution. I keep getting the following error when I try and run LVS on my layout. I think the one time I've gotten it before I was able to work around by solving all the LVS errors by eye as opposed to even looking at...

    Incorrect Instance Error Calibre LVS

    Ugh, cadence is such an awfully made software. (I've gone with a workaround by simply ignoring the padframe on the schematic level and then it passes LVS) On which level of the design would the pin layers make a difference. I've double checked them, but I don't see any that don't match what...

    You'll often end up with situations where there is too much power on the grid and it can actually have to be dissipated as waste. This is because the startup cost and time for a powerplant are a lot more than the running energy to put out the minimum amount of energy. This can lead to weird...

    Calibre LVS"Database cannot be opened", Warning: XDB Database not available: No comparison was made"

    I was trying to solve an LVS error when suddenly I started getting this warning coming up whenever I run LVS. It doesn't seem to come up when I run LVS with other layouts; however, I can't seem to get rid of it. When RVE opens a warning pops up. The warning says: Database cannot be opened XDB...
