Each IO contains an IODELAY module, providing a total of 128 (0~127) delays. The delay may be set statically or dynamically. The delay block is enabled immediately before/after the IO pad. Delay is formally part of IOLOGIC, but can be used without ddr/oser/ides - as shown in the iodelay.v example. The examples blinky-oddr.v and oser4.v are modified to test the new primitive at the same time. Signed-off-by: YRabbit <[email protected]>

Yeah, let's wait until Yosys learns to distinguish between chip families and their primitives and then we'll restart CI for all hung PRs to be sure:) |

Oh I guess they didn't merge that yet huh... |
