  • Publication number: 20220083717
    Abstract: Systems and methods are described herein for attribute-point-based timing formal verification of application specific integrated circuit (ASIC) and system on chip (SoC) designs. A target circuit design having a first set of netlists and timing constraints is received. A plurality of key clock-pin-net-load-setting attributes are extracted from the first ported netlists and timing constraints. The clock-pin-net-load-setting attribute mismatch in the result report is checked between the target circuit design and a golden circuit design by comparing the plurality of target attributes with a plurality of golden attributes of the golden circuit design after the target design database is loaded for static timing analysis (STA).

  • Publication number: 20220012392
    Abstract: Methods, systems, and computer program products are described for generating synthesizable netlists from register transfer level (RTL) designs to aid with semiconductor device design. These netlists provide RTL design information corresponding to a portion of a semiconductor device. A configuration tracer generates behavior information associated with the RTL design. A register compiler compiles a set of semiconductor devices based on one or more technologies and power, performance, and area (PPA) information related to the semiconductor device. Semiconductor devices generated by the register compiler that meet predefined power, performance, and area conditions are identified. Structural information for aligning the input/output ports of the semiconductor device is generated.

  • Patent number: 11177131
    Abstract: Porogen accumulation in a UV-cure chamber is reduced by removing outgassed porogen through a heated outlet while purge gas is flowed across a window through which a wafer is exposed to UV light. A purge ring having specific major and minor exhaust to inlet area ratios may be partially made of flame polished quartz to improve flow dynamics. The reduction in porogen accumulation allows more wafers to be processed between chamber cleans, thus improving throughput and cost.

  • Patent number: 10121682
    Abstract: A purge ring for providing a gas to a wafer processing chamber includes an inlet ring wall defining a ring hole space. An outer perimeter of the inlet ring wall is elliptical. An outer perimeter of the ring hole space is circular. The inlet ring wall is a continuous structure surrounding the ring hole space. An inlet baffle formed within the inlet ring wall surrounds at least 180 degrees of the outer perimeter of the ring hole space. An inlet plenum arranged in a first end of the inlet ring wall provides the gas to the ring hole space through the inlet baffle. An exhaust channel is formed within the inlet ring wall in a second end of the inlet ring wall. An exhaust outlet hole arranged in the second end of the inlet ring wall exhausts the gas out of the ring hole space via the exhaust channel.
