So I'm totally new to this and sorry if this is a really basic question which answer is in the error message. I get the error: [DRC NSTD-1] Unspecified I/O Standard: 5 out of 25 logical ports use I/O standard (IOSTANDARD) value 'DEFAULT', instead of a user assigned specific value. This may cause I/O contention or incompatibility with the board power or connectivity affecting performance, signal integrity or in extreme cases cause damage to the device or the components to which it is connected. To correct this violation, specify all I/O standards.
I know which pins are at fault but I cannot assign them values directly: assignment to a non-net is not permitted.
I've been trying to fix this for a few hours and I'm quite at a loss. I don't want to create a tcl file as it says this may damage the board and this board is quite expensive.
Also this happens when combining two modules. The modules by themselves with the same code run fine. Thanks in advance!
