Introduction history

Network load of concern

It is common knowledge that the X protocol is heavy. With the increase in joint design work across domestic bases, it is possible not only to exchange emails, but also to transfer design data via FTP and use the core system. However, since EDA uses the X protocol, the more users there are, the more traffic it consumes, and if the network becomes overloaded, it may go down. I haven't been able to. "Is it possible to realize the use of EDA across bases without imposing a load on the network?"

Bloated system resource costs

The introduction cost of system resources (application servers, CPU servers, file servers, etc.) installed at each base is increasing year by year. In order to shorten the design cycle and improve quality, the design system itself must be upgraded and expanded, but on the other hand, the costs are skyrocketing. “Is it possible to abolish the system resources installed at local bases and concentrate them at main bases?”

Problem with port used by X protocol

In order to realize the use of EDA across sites, it is necessary to clear communication via firewalls. Naturally, we have firewalls installed at each site, and some of them are also installed within the company LAN to protect design data from unauthorized access. However, since the port used by the X protocol is not fixed (by the way, numbers 6000 and above are used), all the ports to be used must be opened in advance. But then there's no point in having a firewall. "Could it be possible to centralize the ports used by the X protocol?"

Losses due to unexpected network failures

One day, the network was cut off due to a natural disaster. At the same time, the X session during design work was also disconnected, and all the design data and simulation jobs being created by each engineer were blank. The amount of wasted time and effort involved in redesigning is immeasurable. "Is it possible to keep the X session during design work even when the network is disconnected?"

Mobility Solutions

When it comes to large-scale simulation work, it can take from tens of hours to several weeks. Therefore, the computer cannot be turned off while the simulation is running. Also, I would like to check the execution status from other places such as a laboratory, a conference room, or when I am on a business trip to another site. "Is it possible to turn off the computer while running the simulation?"

Benefits

Reduced network load

Communication using Thin X Protocol reduces traffic volume to a minimum of 1/100 compared to conventional PC X servers. It is now possible to design by connecting satellite sites with slow line speeds to the CPU servers of the main design sites in Kanto and Kansai, which was previously difficult to achieve!

Reduce system resource costs

CPU servers, which had previously been required to be installed at each satellite base, were consolidated at the main design bases in Kanto and Kansai. The total number of CPU servers was small, and we were able to reduce the man-hours required to manage equipment at each site, resulting in a significant reduction in TCO!

Resolving X protocol port problems

Combines multiple ports that are never fixed used by the X protocol into two. There is no longer a need to open unspecified ports in the firewall, and the security level has improved!

Backup in case of unexpected failure

X automatically preserves sessions during unexpected network disconnections, keeping X applications running as active sessions, greatly reducing time lost due to system failures!

Mobility Solutions

In addition, since it is possible to temporarily suspend or restore the X session according to the designer's intention, it became possible to use the PC for other work or turn off the power even during long simulation work. !

Improved management capabilities

It is impossible for the administrator himself to check each PC of the designer regarding the number of licenses, version, application of correction patches, etc. of the PC X server used by the designer. was managed by For this reason, it took a lot of time and the cooperation of designers to check information, but by using Server Manager's centralized management function, there was no burden on designers, and the burden on administrators was greatly reduced. I was able to reduce it! "By adopting the next-generation PC X server Exceed onDemand, Renesas Technology has not only dramatically improved the work efficiency of designers, but also reduced TCO!"
