Dear Community,

In OrCAD X Profession, the workspace feature enables the users to store the libraries (Schematic Symbol, Footprint and PSpice Models) and Designs (Schematic and PCB layout) in the cloud workspace.

But storing these libraries and design are stored in servers in the USA, Europe, Asia and Japan Servers.

I don't want to store my designs in any of these servers instead I want to create the workspace in my local PC and store all my libraries and designs in the local workspace.

Is this possible, if possible then can anyone provide the steps/procedure or videos of how to do it?

Regards,

Rohit Rohan

Hai Community,

What are the differences between the Cadence OrCAD / Allegro 24.1 with the Altium Designer 24.

Can I get the grid matrix difference between these two tools?

Optimizing PCB thermal performance is essential in today’s high-density designs, as it ensures stability, prolongs component life, and prevents potential thermal issues. One of the first steps to achieving this is with strategic component placement. Positioning high-power components—such as regulators, power transistors, or processors—away from heat-sensitive parts can prevent thermal interference, and placing them near the edges of the PCB often helps dissipate heat more effectively. It’s also beneficial to group components by their heat generation, creating dedicated thermal zones that can manage localized heating and reduce impact on other areas of the board.

Using thermal vias is another effective technique. By placing thermal vias under components like BGAs or power ICs, heat can be transferred from the surface to internal layers or ground planes. Increasing the size and number of these vias, or using thicker plating, enhances heat conductivity and helps manage heat more evenly across layers in multilayer boards. Increasing copper thickness on the PCB also has a major impact. Opting for thicker copper layers (e.g., 2 oz or even 3 oz copper) significantly boosts the heat dissipation capabilities of power planes and traces, especially in high-current areas. Large copper planes, such as dedicated ground or power planes, are equally effective in spreading heat efficiently. Adding thermal pads directly beneath heat-generating components improves this heat distribution.

Thermal relief pads help regulate heat flow for through-hole components by controlling heat transfer, which reduces thermal stress during soldering and prevents excessive heat spread to nearby sensitive areas. Performing thermal analysis with software tools like Celsius can be invaluable, as it allows you to simulate and model heat distribution, spot potential thermal issues, and refine your design before finalizing it.

Using heat sinks and thermal pads provides a direct way to draw heat from high-power components. Heat sinks can be attached with thermal adhesives, screws, or clamps, while thermal interface materials (TIMs), such as thermal pads or conductive adhesives, further reduce thermal resistance, enhancing heat-transfer efficiency. Optimizing the PCB layer stackup is also a key factor. Dedicated ground and power layers improve heat conduction across the PCB, enabling heat transfer between layers, particularly in high-density and multilayer PCBs.

In designs with high power requirements, active cooling options like fans, blowers, or heat pipes can be essential, helping to direct airflow across the PCB and further improving heat dissipation. Adding ventilation slots around hot zones and considering passive cooling paths enhance natural airflow, making the design more thermally efficient. By combining several of these techniques, you can create a PCB that handles heat effectively, resulting in a robust, long-lasting, and reliable product.

Let us know if you’ve had any challenges with thermal management in your designs—I’d be glad to discuss further!

Socionext, a leader in SoC design, recently made significant strides in enhancing its design efficiency for a complex billion-gate project. Faced with the initial challenges of lengthy eight-day iterations and a protracted two-month timing signoff process, the objective was to reduce the iteration cycle to just three days. By integrating Cadence's cutting-edge solutions—Certus Closure Solution, Tempus Timing Solution, and Quantus Extraction Solution—Socionext achieved remarkable improvements.

Notably, the Tempus DSTA tool dramatically cut timing closure time by 73%, outperforming conventional single-machine STA methods. This achievement, combined with the synergistic use of Cadence's Certus Closure and Tempus Timing solutions, allowed Socionext to meet their ambitious three-day iteration target and double productivity. Additionally, integrating these solutions significantly decreased both human and machine resource needs, slashing memory and disk costs by up to 90% and halving engineering resources during the optimization and signoff phases.

Conformal ECO Designer enables you to implement RTL engineering change orders (ECOs) for pre- and post-mask layout and offers early ECO prototyping capabilities for driving critical project decisions.

Conformal ECO compares two designs and generates a functional patch that implements the changes between the two designs.

One major criterion for determining patch quality is whether the patch can meet timing closure. To determine this, you typically need to run the time-consuming process of incremental synthesis and place-and-route. Instead, Conformal can analyze path logic depth changes before and after ECO patch generation. This provides a faster way to evaluate timing impact in patch generation stages.

After the patch is created and applied, it is passed to Genus to optimize the patch.

During patch optimization, you can choose to do many things like:

• Keeping constants in the patch
• Allowing tie cell inversion
• Specifying tie cell types
• Preserve DFF cells and cell types in the patch
• Preserve all cells and nets in the patch
• Preserve clock buffer cell in the patch
• Turn on/off sequential constant and sequential merge in patch optimization
• Allowing phase mapping for DFFs
• Map to spare cells
• Force fix DRC before timing

LONDON — The head of the Church of England, spiritual leader of the global Anglican Communion, is under pressure to resign after an investigation found that he failed to inform police about serial physical and sexual abuse by a volunteer at Christian summer camps as soon as he became aware of it. Some members of the General Synod, the church's national assembly, have started a petition calling on Archbishop of Canterbury Justin Welby to step down, saying he had "lost the confidence of his clergy." The petition had garnered more than 1,800 signatures on Change.org by late morning London time on Monday. Compounding the pressure, a senior cleric added her voice to those who believe he should resign. Helen-Ann Hartley, the bishop of Newcastle, told the BBC that Welby's position is "untenable.'' Calls for Welby's resignation have grown since Thursday, when the church released the results of an independent review into John Smyth, who sexually, psychologically and physically abused about 30 boys and young men in the United Kingdom and 85 in Africa over five decades. The 251-page report concluded that Welby failed to report Smyth to authorities when he was informed of the abuse in August 2013, soon after he became Archbishop of Canterbury. Welby last week took responsibility for not ensuring that the allegations were pursued as "energetically" as they should have been after he learned of the abuse but said he had decided not to resign. On Monday, his office issued a statement reiterating Welby's "horror at the scale of John Smyth's egregious abuse." "As he has said, he had no awareness or suspicion of the allegations before he was told in 2013 — and therefore, having reflected, he does not intend to resign," the statement said. "He hopes the Makin Review supports the ongoing work of building a safer church here and around the world." Church officials were first made aware of the abuse in 1982, when they received the results of an internal investigation into Smyth. The recipients of that report "participated in an active cover-up" to prevent its findings from coming to light, the Makin Review found. Between 1984 and 2001, Smyth moved to Zimbabwe and subsequently relocated to South Africa. He continued to abuse boys and young men in Zimbabwe and there is evidence that the abuse continued in South Africa until he died in August 2018. Smyth's abuse wasn't made public until a 2017 investigation by Britain's Channel 4 television, which led Hampshire Police to start an investigation. Police were planning to question Smyth at the time of his death and had been preparing to extradite him. The Makin Review found that if Smyth had been reported to police in 2013, it could have helped to uncover the truth, prevented further abuse and led to a possible criminal conviction. "In effect, three and a half years was lost, a time within which John Smyth could have been brought to justice and any abuse he was committing in South Africa discovered and stopped," the review found. The Archbishop of Canterbury is the head of the Church of England and is seen as the spiritual leader of the Anglican Communion, which has more than 85 million members in 165 countries. He is considered first among equals with respect to the communion's other primates.

London — Archbishop of Canterbury Justin Welby, head of the Church of England and spiritual leader of the global Anglican Communion, resigned Tuesday after an investigation found that he failed to tell police about serial physical and sexual abuse by a volunteer at Christian summer camps as soon as he became aware of it.  Pressure on Welby had been building since Thursday, when release of the inquiry's findings kindled anger about a lack of accountability at the highest reaches of the church. Helen-Ann Hartley, the bishop of Newcastle, said Monday that his position was "untenable" after some members of the church's national assembly started a petition calling on Welby to step down because he had "lost the confidence of his clergy."  "I believe that stepping aside is in the best interests of the Church of England, which I dearly love and which I have been honored to serve," Welby said in a statement.  The strongest outcry came from the victims of John Smyth, a prominent attorney who abused teenage boys and young men at Christian summer camps in Britain, Zimbabwe and South Africa over five decades. Andrew Morse, who was repeatedly beaten by Smyth over a period of five years, said that resigning was a chance for Welby to start repairing the damage caused by the church's handling of historical abuse cases more broadly.  "I believe that now is an opportunity for him to resign,'' Morse told the BBC before Welby stepped down. "I say opportunity in the sense that this would be an opportunity for him to stand with the victims of the Smyth abuse and all victims that have not been treated properly by the Church of England in their own abuse cases."  Welby's resignation comes against the backdrop of widespread historical sexual abuse in the Church of England. A 2022 report by the Independent Inquiry Child Sexual Abuse found that deference to the authority of priests, taboos surrounding the discussion of sexuality and a culture that gave more support to alleged perpetrators than their victims helped make the Church of England Church of England "a place where abusers could hide."
