numbering convention.
Quartus II software.
The anchor point, or origin, in Stratix and Stratix GX devices is in the
bottom-left corner, instead of the top-left corner as in APEX II and
APEX 20K devices.
The anchor point, or origin, of a large block element (e.g., a M-RAM
or DSP block) is also the bottom-left corner.
All numbers are zero-based, meaning the origin at the bottom-left of
the device is X0, Y0.
The I/O pins constitute the first and last rows and columns in the
X-Y coordinates. Therefore, the bottom row of pins resides in
X<number>, Y0, and the first left column of pins resides in X0,
Y<number>.
The sub-location of elements, N, numbering begins at the top.
Therefore, the LEs in an LAB are still numbered from top to bottom,
but start at zero.
