Link circuit modules
--------------------
Each defined SPICE model should be linked to a FPGA module defined in the original part of architecture descriptions. It helps FPGA-SPICE creating the SPICE netlists for logic/routing blocks. Since the original part lacks such support, we create a few XML properties to link to SPICE models.

SRAM

Switch Blocks

Create Customized SPICE Modules
===============================
To make sure the customized SPICE netlists can be correctly included in FPGA-SPICE, the following rules should be fully respected:
1. The customized SPICE netlists could contain multiple sub-circuits but the names of these sub-circuits should not be conflicted with any reserved words.. Here is an example of defining a sub-circuit in SPICE netlists. The <subckt_name> should be a unique one, which should not be conflicted with any reserved words.
.subckt <subckt_name> <ports>
2. The ports of sub-circuit to be included should strictly follow the sequence:
<input_ports> <output_ports> <sram_ports> <clock_ports> <vdd> <gnd>
It is not necessary to keep the names of ports be the same with what is defined in the SPICE models. But the bandwidth of the ports should be consistent with what is defined in the SPICE models.
It is not necessary to keep the names of ports be the same with what is defined in the SPICE models. But the bandwidth of the ports should be consistent with what is defined in the Circuit models.
If the customized SPICE netlists includes inverters, buffers or transmission gates, it recommended to use those auto-generated by FPGA-SPICE. It is also recommend to use the transistor sub-circuit (vpr_nmos and vpr_pmos) auto-generated by FPGA-SPICE. In the appendix, we introduce how to use these useful sub-circuits.

With the 96 nm half pitch, such wires would take 60 um of height, vs. a 90 nm high (approximated as square) Stratix IV tile so this seems
reasonable. Using a tile length of 90 nm, corresponding to the length of a Stratix IV tile if it were square. -->

With the 96 nm half pitch, such wires would take 60 um of height, vs. a 90 nm high (approximated as square) Stratix IV tile so this seems
reasonable. Using a tile length of 90 nm, corresponding to the length of a Stratix IV tile if it were square. -->

With the 96 nm half pitch, such wires would take 60 um of height, vs. a 90 nm high (approximated as square) Stratix IV tile so this seems
reasonable. Using a tile length of 90 nm, corresponding to the length of a Stratix IV tile if it were square. -->
