Publication number: 20160004797Abstract: In circuit designing of a semiconductor integrated circuit or the like, reworks accompanying returning from the backend layout design are reduced, so that efficiency improvement (time reduction) of the entire development can be achieved. A high-level synthesis processing part conducts high-level synthesis of behavioral description. The synthesis result analyzing part acquires a layout designing condition being a condition concerning layout designing of a designing target circuit, and compares the layout designing condition with a high-level synthesis result. If any one element included in the high-level synthesis result is different from the layout designing condition, the synthesis result analyzing part decides a changing method of changing the hierarchical structure of the behavioral description. A hierarchy changing part changes the hierarchical structure of the behavioral description in accordance with the changing method decided by the synthesis result analyzing part.Type: ApplicationFiled: June 30, 2015Publication date: January 7, 2016Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Susumu HIRANO, Ryo YAMAMOTO

Publication number: 20040019830Abstract: A test apparatus has a scan path consisting of scan flip-flops connected in a shift register fashion. Any two adjacent scan flip-flops include clock generating circuits for generating clock signals for shifting scan data at a rising edge and a falling edge of the clock signals in a test scan mode, respectively. Each clock generating circuit further includes a scan flag generator for generating a scan flag for halting the clock signal of the scan flip-flop. The test apparatus can prevent a hold error due to clock skew without complicating the design process, and with a simple circuit configuration.Type: ApplicationFiled: January 24, 2003Publication date: January 29, 2004Applicant: Mitsubishi Denki Kabushiki Kaisha.Inventors: Shiro Hosotani, Susumu Hirano

Patent number: 5190163Abstract: A sorting apparatus is disclosed which utilizes transmitted light to determine whether or not an article under inspection is defective in order to reject any article determined to be defective. A light irradiator is provided on irradiating an article being inspected with a light beam having a smaller diameter than that of an article, and a light condenser is provided for condensing the rays of light transmitted through the article while being diffused. Two light detectors respectively detect two specific kinds of light having different wavelengths from among the condensed rays of light transmitted through the article.
