System Validation Rule Trigger Order of Execution

HI Guys ,
 I need to understand few things regarding Execution Rule 
As per I understand below is Order
System Validation 
Before Trigger
Custom Validation 

When we are saying system validation is this only Layout Specific(Like made field required on layout) System validation  or including Validation lets we have mad field required during its creation ?

I was trying few thing like i created a field and made it required through before Trigger and Then Made it Blank again in after trigger so record is saving properly but when i made field required during field creation and i am trying to make it blank in after trigger then it is throwing error required field missing although system validation happens  before  after trigger .

Can anybody please explain ?

If you have System validation rule(like making field mandatory on field creation) on any field then system will not allow you to insert or update record through trigger/apex/dataloader. You need to provide value in that mandatory field.
Hi Abhi , I am more concerened about execution order if we are obeying the execution order then system should allow ?
