Subject: [openrisc] problem with clk signals
Hi Erno,a solution can be remove completely the ISE 6.1 software, and
reinstall it. We found that previous Webpack might cause such errors
(it is not sure), but the problem disappeared.

ps: the idea came from that exactly the same project file was error
free on another PC.
