CLOCK_SPINE

Specifies the Spine Clock (SCLK) wire index to use for the targeted global signal. Each clock sector contains 32 SCLK resources, and an allocated global clock tree will use the same SCLK index in each driven clock sector. This is an advanced assignment that can potentially be useful to control global signal routing decisions in cases of global resource congestion. When used, this assignment should typically be paired with a Clock Region assignment to ensure the driven clock sectors are also constrained.
