Problem Title:
Exemplar Leonardo Spectrum v1999.1c: ngdhelpers:312 - logical block of type GND is
unexpanded
Problem Description:
urgency : standard
problem description: When a design is synthesized with version 1999.1c of
Leonardo Spectrum, the netlist gives an unexpanded block error in
ngdbuild for the GND component.
The affected families are all Xilinx XC3000, XC3100, XC5200 and all xc4000
variants, Spartan and SpartanXL.
Solution 1:
This is a problem with the Leonardo tool generating an incorrect port name
for the gnd component.
The exported netlist contains a Xilinx GND component who's port is
named 'O'. The port name should be 'G'.
This problem has been fixed since ExemplarSpectrum 1999.1d.
