Chipbond and Taiwan team reached strategic cooperation agreement for IGBT project
On August 9, 2019, Shenzhen Chipbond Technology and Taiwan's IGBT project team formally signed an investment agreement, which will establish Chipbond Holding's subsidiary to enter the IGBT field! The Taiwan IGBT project team has rich R & D experience in the industry, and masters the innovative technology of IGBT products. I believe that the explosion of new products in the future is just around the corner!

Gated Clock-Practical Study
Gated Clock-Practical Study
Time of issue : 2014-04-20 15:18:00
Gated clock-actual research July 3, 2010 4bit counter with enable, including positive edge trigger and negative edge trigger; 1. Functional simulation: 1. Circuit structure and simulation waveform: 2. Insert ICG with latch (integrated gate) Control): 1. Synthesis script: 2. Gated synthesis result: 3. Simulation waveform: 3. Insert ICG without latch: 1. Synthesis script: 1. Need to find whether there is ICG without latch in the library; 2. The corresponding gated units of the rising edge trigger register and the falling edge trigger register need to be selected separately; 3. Script: 2. Synthesis result: 3. Simulation timing diagram: 4. Note: 1. Only the rising edge output is enabled (this enables It can be any combination of the rising edge signals of a clock output.) Registers that control the rising edge can be inserted into the rising edge type ICG. 2. Only the falling edge output is enabled. Any combination of the rising edge signal of the clock output can be used.) Only the falling edge type ICG can be inserted into the register that triggers the falling edge. , You need to instantiate the ICG manually Or write gating logic gating. 4. If the synthesis script is changed to the following script, the synthesis will be maintained, and the result will be inserted into the ICG with latch structure; 4. Insert the discrete gate with latch: 1. Gate integrated script: 2. Gate integrated result: 3 . Emulation waveform: 5. Insert discrete gate without latch: 1. Integrated pin

How to ensure the quality of verification-revised draft
How to ensure the quality of verification-revised draft
Verification on February 28, 2010 is a guarantee of design quality, and no design can run accurately without verification. Therefore, it is very important to verify how to ensure the quality. The whole verification work is mainly manifested in two aspects in form: 1. Verification points; 2. Verification environment (including test cases) Verification environment is the carrier of verification points and the specific implementation of verification points. For the project, it also includes the organization of the verification. The qualification of the verified organizer will determine whether the verification of the real project can be carried out smoothly. For verification points, its focus is completeness; for verification environments, its focus is
