Initiate Floorplan<br />
• Set the two environment variables to ensure io row and<br />
corner row contact tightly.<br />
Set var plan.iorow.snapgrid.x 1<br />
Set var plan.iorow.snapgrid.y 1<br />
• Enable Flip Every Other Row and Abut Rows with Row<br />
Spacing “0” on Core Area Parameters.<br />
• Let Block Halo Per Side the same as IO to Core Distance.<br />
– Analog Block includes power rails, SE just can offer one power<br />
rails for digital block.<br />
• SE automatically calculate the core area form given value.<br />
• In C<strong>IC</strong> 0.35 process, METAL1 and METAL3 are defined<br />
as horizontal routing layers, METAL2 and METAL4 are<br />
defined as vertical routing layers.<br />
