Problem Title:
F1.4 Schematic: "Create schematic from netlist" loses INV from symbols in XNF file
Problem Description:
Urgency: Standard
General Description:
When "Create schematic from netlist" is used to create a schematic from an XNF
netlist, the Foundation schematic that is created does not include the INV pin
property from symbols in XNF file.
Example: The AND symbol below should be converted to an AND2B2 or an AND2 with
two inverters on the inputs. Instead it is converted to an AND2 with no invertions.
SYM, AND_invs, AND, LIBVER=2.0.0
PIN, I0, I, input1,,INV
PIN, I1, I, input2,,INV
PIN, O, O, out1
END
Solution 1:
The only current workaround is to replace INV pin properties in
the XNF file with inverter symbols.
Example:
Original:
SYM, AND_invs, AND, LIBVER=2.0.0
PIN, I0, I, inv1_out
PIN, I1, I, inv2_out
PIN, O, O, out1
END
Converted:
SYM, AND_invs, AND, LIBVER=2.0.0
PIN, I0, I, input1,,INV
PIN, I1, I, input2,,INV
PIN, O, O, out1
END
SYM, inv1, INV, LIBVER=2.0.0
PIN, I, I, input1
PIN, O, O, inv1_out
END
SYM, inv2, INV, LIBVER=2.0.0
PIN, I, I, input1
PIN, O, O, inv2_out
END
