Peripheral Component Interconnect Express (PCIe) is a high-speed interface standard widely used for connecting processors, memory, and peripherals. With the increasing reliance on PCIe to handle sensitive data and critical high-speed data transfer, ensuring data integrity and encryption during verification is the most essential goal. As we know, in the field of verification, randomization is a key technique that drives robust PCIe verification. It introduces unpredictability to simulate real-world conditions and uncover hidden bugs from the design. This blog examines the significance of randomization in PCIe IDE verification, focusing on how it ensures data integrity and encryption reliability, while also highlighting the unique challenges it presents. For more relevant details and understanding on PCIe IDE you can refer to Introducing PCIe's Integrity and Data Encryption Feature . The Importance of Data Integrity and Data Encryption in PCIe Devices Data Integrity : Ensures that the transmitted data arrives unchanged from source to destination. Even minor corruption in data packets can compromise system reliability, making integrity a critical aspect of PCIe verification. Data Encryption : Protects sensitive data from unauthorized access during transmission. Encryption in PCIe follows a standard to secure information while operating at high speeds. Maintaining both data integrity and data encryption at PCIe’s high-speed data transfer rate of 64GT/s in PCIe 6.0 and 128GT/s in PCIe 7.0 is essential for all end point devices. However, validating these mechanisms requires comprehensive testing and verification methodologies, which is where randomization plays a very crucial role. You can refer to Why IDE Security Technology for PCIe and CXL? for more details on this. Randomization in PCIe Verification Randomization refers to the generation of test scenarios with unpredictable inputs and conditions to expose corner cases. In PCIe verification, this technique helps us to ensure that all possible behaviors are tested, including rare or unexpected situations that could cause data corruption or encryption failures that may cause serious hindrances later. So, for PCIe IDE verification, we are considering the randomization that helps us verify behavior more efficiently. Randomization for Data Integrity Verification Here are some approaches of randomized verifications that mimic real-world traffic conditions, uncovering subtle integrity issues that might not surface in normal verification methods. 1. Randomized Packet Injection: This technique randomized data packets and injected into the communication stream between devices. Here we Inject random, malformed, or out-of-sequence packets into the PCIe link and mix valid and invalid IDE-encrypted packets to check the system’s ability to detect and reject unauthorized or invalid packets. Checking if encryption/decryption occurs correctly across packets. On verifying, we check if the system logs proper errors or alerts when encountering invalid packets. It ensures coverage of different data paths and robust protocol check. This technique helps assess the resilience of the IDE feature in PCIe in below terms: (i) Data corruption: Detecting if the system can maintain data integrity. (ii) Encryption failures: Testing the robustness of the encryption under random data injection. (iii) Packet ordering errors: Ensuring reordering does not affect data delivery. 2. Random Errors and Fault Injection: It involves simulating random bit flips, PCRC errors, or protocol violations to help validate the robustness of error detection and correction mechanisms of PCIe. These techniques help assess how well the PCIe IDE implementation: (i) Detects and responds to unexpected errors. (ii) Maintains secure communication under stress. (iii) Follows the PCIe error recovery and reporting mechanisms (AER – Advanced Error Reporting). (iv) Ensures encryption and decryption states stay synchronized across endpoints. 3. Traffic Pattern Randomization: Randomizing the sequence, size, and timing of data packets helps test how the device maintains data integrity under heavy, unpredictable traffic loads. Randomization for Data Encryption Verification Encryption adds complexity to verification, as encrypted data streams are not readable for traditional checks. Randomization becomes essential to test how encryption behaves under different scenarios. Randomization in data encryption verification ensures that vulnerabilities, such as key reuse or predictable patterns, are identified and mitigated. 1. Random Encryption Keys and Payloads: Randomly varying keys and payloads help validate the correctness of encryption without hardcoding assumptions. This ensures that encryption logic behaves correctly across all possible inputs. 2. Randomized Initialization Vectors (IVs): Many encryption protocols require a unique IV for each transaction. Randomized IVs ensure that encryption does not repeat patterns. To understand the IDE Key management flow, we can follow the below diagram that illustrates a detailed example key programming flow using the IDE_KM protocol. Figure 1: IDE_KM Example As Figure 1 shows, the functionality of the IDE_KM protocol involves Start of IDE_KM Session, Device Capability Discovery, Key Request from the Host, Key Programming to PCIe Device, and Key Acknowledgment. First, the Host starts the IDE_KM session by detecting the presence of the PCIe devices; if the device supports the IDE protocol, the system continues with the key programming process. Then a query occurs to discover the device’s encryption capabilities; it ensures whether the device supports dynamic key updates or static keys. Then the host sends a request to the Key Management Entity to obtain a key suitable for the devices. Once the key is obtained, the host programs the key into the IDE Controller on the PCIe endpoint. Both the host and the device now share the same key to encrypt and authenticate traffic. The device acknowledges that it has received and successfully installed the encryption key and the acknowledgment message is sent back to the host. Once both the host and the PCIe endpoint are configured with the key, a secure communication channel is established. From this point, all data transmitted over the PCIe link is encrypted to maintain confidentiality and integrity. IDE_KM plays a crucial role in distributing keys in a secure manner and maintaining encryption and integrity for PCIe transactions. This key programming flow ensures that a secure communication channel is established between the host and the PCIe device. Hence, the Randomized key approach ensures that the encryption does not repeat patterns. 3. Randomization PHE: Partial Header Encryption (PHE) is an additional mechanism added to Integrity and Data Encryption (IDE) in PCIe 6.0. PHE validation using a variety of traffic; incorporating randomization in APIs provided for validating PHE feature can add more robust Encryption to the data. Partial Header Encryption in Integrity and Data Encryption for PCIe has more detailed information on this. Figure 2: High-Level Flow for Partial Header Encryption 4. Randomization on IDE Address Association Register values: IDE Address Association Register 1/2/3 are supposed to be configured considering the memory address range of IDE partner ports. The fields of IDE address registers are split multiple values such as Memory Base Lower, Memory Limit Lower, Memory Base Upper, and Memory Limit Upper. IDE implementation can have multiple register blocks considering addresses with 32 or 64, different registers sizes, 0-255 selective streams, 0-15 address blocks, etc. This Randomization verification can help verify all the corner cases. Please refer to Figure 2. Figure 3: IDE Address Association Register 5. Random Faults During Encryption: Injecting random faults (e.g., dropped packets or timing mismatches) ensures the system can handle disruptions and prevent data leakage. Challenges of IDE Randomization and its Solution Randomization introduces a vast number of scenarios, making it computationally intensive to simulate every possibility. Constrained randomization limits random inputs to valid ranges while still covering edge cases. Again, using coverage-driven verification to ensure critical scenarios are tested without excessive redundancy. Verifying encrypted data with random inputs increases complexity. Encryption masks data, making it hard to verify outputs without compromising security. Here we can implement various IDE checks on the IDE callback to analyze encrypted traffic without decrypting it. Randomization can trigger unexpected failures, which are often difficult to reproduce. By using seed-based randomization, a specific seed generates a repeatable random sequence. This helps in reproducing and analyzing the behavior more precisely. Conclusion Randomization is a powerful technique in PCIe verification, ensuring robust validation of both data integrity and data encryption. It helps us to uncover subtle bugs and edge cases that a non-randomized testing might miss. In Cadence PCIe VIP, we support full-fledged IDE Verification with rigorous randomized verification that ensures data integrity. Robust and reliable encryption mechanisms ensure secure and efficient data communication. However, randomization also brings various challenges, and to overcome them we adopt a combination of constrained randomization, seed-based testing, and coverage-driven verification. As PCIe continues to evolve with higher speeds and focuses on high security demands, our Cadence PCIe VIP ensures it is in line with industry demand and verify high-performance systems that safeguard data in real-world environments with excellence.

Hello..

I'm updating part in part editor in orcad capture, and I wonder how to align pin numbers using menu or tcl/tk command.

Please, let me know. Thank you.

Hello All,

I'm a novice to this forum and probably this subject has been already discussed here.

My company has purchased OrCAD Capture 17.4 tools that have a new GUI if compared to my earlier used OrCAD Capture 9.2. I have been using Capture 9.2 for ~18 years and its GUI is really convenient. The GUI of 17.4 looks to be a modern one with new icons and really has improved features and new capabilities.

However, my main complain about GUI 17.4 is that the schematic windows cannot be cascaded. Although they can be set floating, this is even more annoying because all toolbars remain in the Capture window and when you select a tool, the Capture window pops over already open schematic window and you need a lot of useless extra clicks to return back to the currently edited schematic page. I always used cascading of schematic windows before because my complex designs includes many pages, not speaking about the library windows that are typically open simulatneously. My view is that the lack of CASCADING in Capture GUI 17.4 is critical and unacceptable for complex projects, and I would very highly appreciate if the Cadence guys will return back the CASCADING capability for schematic pages. In case this will be done, this will make the GUI really great and comfortable to use.

Does anybody have opinion on this issue?

Many thanks,

Pavel

President Joe Biden and Indonesian President Prabowo Subianto met Tuesday at the White House to strengthen U.S.–Indonesia ties. The meeting came days after Jakarta signed a maritime agreement with Beijing that critics say could lend credibility to China’s “nine-dash line” that reflects its expansive claims in the South China Sea. White House Bureau Chief Patsy Widakuswara has this report

white house — President Joe Biden and President Prabowo Subianto met Tuesday at the White House, marking the 75th anniversary of U.S.-Indonesia relations, part of a multination visit by the newly inaugurated leader of Southeast Asia's largest economy. "I will work very hard to strengthen Indonesia and United States relationship," said Prabowo, who goes by his first name. Biden said he looks forward to deepening the Comprehensive Strategic Partnership, the highest level among nontreaty allies, which the two countries signed in 2023. "That includes deepening our security cooperation," he said before their meeting. In brief remarks to the press, Biden twice raised an issue of concern for Washington: freedom of navigation in the South China Sea. He said he wanted to strengthen the U.S. partnership with Indonesia, "by advancing [a] free and open Indo-Pacific." "We'll discuss, also, global challenges, including in Gaza and the South China Sea," he said. China's nine-dash line The White House meeting came days after Prabowo's meeting with Chinese President Xi Jinping in Beijing, where Indonesia and China signed a series of agreements valued at about $10 billion and focusing on infrastructure, green energy, digital technology and agriculture. "In the present situation, geopolitical and geoeconomic, Indonesia and China have become very close partners in many, many fields," Prabowo said. One of the deals is to jointly develop fisheries, and oil and gas exploration in waters around Indonesia's Natuna Islands where China's "nine-dash line" marking its expansive claims in the South China Sea overlaps with Indonesia's Exclusive Economic Zone. Critics say the agreement risks implicitly validating China's territorial claims in the South China Sea, which, according to the United Nations, has no basis in international law. VOA asked the White House whether Biden was specifically referring to this deal in his meeting with Prabowo. "We continue to encourage Indonesia to work with their legal experts to make sure any agreement they make with the PRC [People's Republic of China] is in accordance with international law, especially the U.N. Convention on the Law of the Sea," said White House press secretary Karine Jean-Pierre. Beijing claims the major shipping route almost entirely, infringing into the EEZs of Indonesia, Vietnam, Malaysia, Brunei and the Philippines. All but Indonesia formally dispute the Chinese claim while Taiwan makes a claim to the sea similar to Beijing's. "It's a big deal for Indonesia," as a non-claimant country in the South China Sea dispute that supports the concept of a "free and open Indo-Pacific," said Klaus Heinrich Raditio, author on South China Sea issues and lecturer at Indonesia's Driyarkara School of Philosophy. "People will question our position," he told VOA. The Indonesian Foreign Ministry clarified Sunday that it remains firm in rejecting China's nine-dash line. Beijing's claim, Jakarta said, "does not comply" with the 1982 United Nations Convention on the Law of the Sea and "therefore has no bearing" on Indonesia's sovereignty and jurisdiction over the North Natuna Sea. Jakarta's agreement with Beijing highlights a "new phase of building the China-Indonesia community with a shared future," according to the joint statement. This reference supports "China's vision of a new global order that is anti-Western hegemony," Raditio said. It's unclear whether this language was an intentional signaling of a geopolitical shift or merely an overlook from a new administration eager to bolster ties with great powers. The Indonesian Embassy in Washington has not responded to VOA's queries. "Most likely, it is a bureaucratic mistake," Raditio said. "We put too much attention on economic cooperation. How many investments that we can attract from China? We kind of sideline other important issues." Prabowo's outreach to Trump Just as important to Jakarta as the White House meeting is Prabowo's outreach to U.S. President-elect Donald Trump. Jakarta is gearing up for Trump's new administration that begins in January. "Wherever you are, I'm willing to fly to congratulate you personally, sir," Prabowo said in a call to Trump that was posted Monday on his social media. The Trump team has not responded to VOA's queries on the conversation. U.S. foreign policy under Trump "may become more transactional and more focused on elements related to U.S.-China, competition," said Andreyka Natalegawa, associate fellow for the Southeast Asia Program at the Center for Strategic and International Studies. "The downside risk of this as it relates to Southeast Asian countries, is that it may limit some of the decision-making space they have in their diplomatic affairs," Natalegawa said. Prabowo has voiced ambitions to raise Indonesia's international profile and has made early foreign policy moves, including a surprise decision to join Southeast Asia's largest economy to the BRICS bloc. BRICS, which stands for Brazil, Russia, India, China and South Africa, is a growing group of emerging economies seen as a counterweight to the West. In October, BRICS added Indonesia as one of the group's 13 new "partner countries." The move could be a shift away from the position taken by Prabowo's predecessor, Joko Widodo, who took in massive amounts of infrastructure investments from Beijing but remained mostly nonaligned geopolitically. The White House visit marks a milestone for Prabowo, who was barred from entering the U.S. under the Clinton, Bush and Obama administrations over his role in abducting activists of the 1998 "Reformasi" movement that ousted President Suharto, Prabowo's then father-in-law. The Trump administration lifted the visa ban for then-Defense Minister Prabowo, for his visit in 2020.
