lattice DIAMOND报 no clock nets in the design.

我用XO3 2100E做的一个MIPI DSI 2 MIPI DSI的案子，编译时出现如下错误：

WARNING – intosc matches no clock nets in the design. This preference has been disabled.
ERROR – ‘iclkhs’ matches no clock ports in the design.
ERROR – intosc matches no clock nets in the design.
ERROR – Port ‘iresetn’ is unconnected.
