Tham khảo tài liệu 'advances in analog circuits part 11', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | Analog-aware Schematic Synthesis 289 Rule extraction for new circuit Rule extraction from new circuits accepts the schematic rules from companion circuits and new circuit netlist mainly goes through the five steps pre-processing tracing direct current paths tracing signal flow paths exploring structural features and exploring schematic rules from structural feature analogy and outputs the schematic rules for new circuits as shown in c of Fig 55. Most of the steps are same as previous descriptions except exploring schematic rules from structural feature analogy. Exploring schematic rules from structural feature analogy can be done on device level direct current path branch level direct current path level block level and more high level and in procedure the exploration should be started from low level structural feature comparison to high level structure feature comparison. If a group of devices in new circuit has the same structural feature as a group of devices in companion circuits the schematic rules for the group of devices in companion circuits will be copied for the group of devices in the new circuit. If a direct current path in new circuit has the same structural feature as a direct current path in companion circuits the schematic rules for the direct current path in companion circuits will be copied for direct current path in the new circuit. If a block in new circuit has the same structural feature as a block in companion circuits the schematic rules for the block in companion circuits will be copied for block in the new circuit. If a new circuit has the same structural feature as a companion circuit the schematic rules for the companion circuit will be copied for the new circuit. Rule application for new circuit schematic synthesis Rule application for new circuit schematic synthesis accepts the net circuit netlist and the schematic rules for new circuit mainly goes through the five steps constraint generation merge constraints with schematic .
