Routing fails without explicitly inserted BUFG on clock

5

I am trying to synthesize a very simple circuit, targeting `xc7a50tcsg324-1`. I can take the same input and synthesize all the way to a bitfile with Vivado. VPR fails with...

Alongside with [reading the logical netlist](https://github.com/SymbiFlow/vtr-verilog-to-routing/issues/568), once P&R has been completed, VPR should be able to produce a physical netlist as well, probably using a similar approach as for `genfasm`

VPR is able to only read the eblif at the moment, and, to support operating on interchange-based netlist it would need to be enhanced with another library to read it.

Need FPGA device database backend from VPR

1

The VPR architecture XML and RR graph should be enough information to generate an FPGA interchange device database.

Net alias not properly considered when creating set_{min,max}_delay constrainst

4

Alias are not considered when processing the `get_clocks` call when doing min/max delay constrainsts in the SDC. #### Expected Behaviour In the input netlist where you have theses aliases :...
