I did connect global power nets to all pins. Then did sroute. Then added the standard cells. And the geometry check gives me this errors, thousands of them:
Blockage of Cell U_BUF2/URAM/ram_reg
bbox = (322.540, 1477.810) (322.600, 1478.170)
I am attaching picture pointing to the error with arrow. The blue lines you see are M1 VDD! and GND! lines, and I have checked the standard cell layout and confirmed that those power lines correctly overlap the power lines of standard cells.
I am not quite getting why the error checker is not happy and what kind of blockage of cell is it talking about? Whst exactly is blocked?
