hi @Tim Edwards @Mitch Bailey , when i load the top.mag file , getting below crosses : does the below warning mean its deleting the cells ?? Duplicate cell in RRAM_CONTROLLER: Instance of cell sky130_fd_sc_hd__diode_2.mag is from path /usr/local/share/pdk/sky130B/libs.ref/sky130_fd_sc_hd/mag but cell was previously read from runs/run4_gds1/results/signoff. Cell name conflict: Renaming original cell to sky130_fd_sc_hd__diode_2#0. Duplicate cell in RRAM_CONTROLLER: Instance of cell sky130_fd_sc_hd__decap_3.mag is from path /usr/local/share/pdk/sky130B/libs.ref/sky130_fd_sc_hd/mag but cell was previously read from runs/run4_gds1/results/signoff. Cell name conflict: Renaming original cell to sky130_fd_sc_hd__decap_3#0. Duplicate cell in RRAM_CONTROLLER: Instance of cell sky130_fd_sc_hd__tapvpwrvgnd_1.mag is from path /usr/local/share/pdk/sky130B/libs.ref/sky130_fd_sc_hd/mag but cell was previously read from runs/run4_gds1/results/signoff. Cell name conflict: Renaming original cell to sky130_fd_sc_hd__tapvpwrvgnd_1#0. , RRAM_CONTROLLERWarning: Parent cell lists instance of "RRAM_ANALOG" at bad file path runs/run4_gds1/results/signoff/RRAM_ANALOG.mag.

The crosses do mean that cells were not found, because there's no bounding box associated with them; but the warnings of cells not being found where specified but found in the installed PDK should not be relevant. There must be somewhere that a cell is not being found at all. If you select the cross and type

what

, it should tell you what it thinks that instance was supposed to be, so you can figure out what cell (or cells) was missing.
