Simplex Knowledge Base

[Carmelina Olden]

I'm trying to allocate a 8 lanes tx and a 4 lanes rx in the E-tile bank 9A connecting to the same QSFPDD1 (8 pins for tx_serial[] output ports and 4 pins for rx_serial[] output ports) as shown in the figure 1. Since by default, when using IP JESD204C simplex transmitter and receiver IPs, the coupled-pair rx or tx channel are tied off, I want to merge multiple jesd204C IP blocks to maximize transceiver channel utilization. I used wire-level connections in platform designer to allow the transceiver TX and RX PHYs to share the same address space, figure 2 ( -resources/knowledge-base/hsio/2020/how-do-i-merge-simplex-transceiver-phys-inside-the-intel--quartu.html ) and also I added XCVR_RECONFIG_GROUP in the QSF assignments as follows:

As I understand it, you have some inquiries merging of simplex instances. Based on my understanding, the two instance will need to be of the same number of channel. To facilitate the debugging, I would recommend you to start with two 4 channels simplex instances in RTL and try on the merging. Once it is successful, you may move to Platform Designer to try out merging. This would be helpful to narrow down issues if there is any arise.

I tried merging simplex transmitter and receiver PHY (4T4R) and it still gives the same error about pin conflicts. In page 37 of _jesd204b.pdf , it says "For simplex variants with E-tile transceiver, the underneath transceiver is in duplex mode. The merging of independent TX and RX within a transceiver channel is not supported in this version",

Thanks for your update and clarification that you are using E-Tile transceivers. For your information, due to the underneath architecture, when E-Tile is put to simplex mode, the unused pair (TX or RX) will be powered down. This restriction is tile dependent. Therefore, in the Agilex E-tile, similar restriction should apply. Sorry for the inconvenience. As a workaround, you might want to explore H-Tile if you merging is required.

Thanks for your clarification! One more question, when I read the JESD204C intel IP document, it says that Device Support on the JESD204C is Agilex (e-tile) or Stratix 10 (e-tile), shown in the attached screenshot. Does this mean that I cannot use H-tiles for JESD204C? So I can only pick either to merge simplex PHY (H-tiles) or using JESD204C IP block (E-tiles)?

The majority of fiber optic cable installed for audio, video, network and control is two strand (duplex) count or greater. This is because most fiber optic electronics, including SFP modules, segregate send and receive signal transmission onto two separate fiber strands.

Simplex (or one strand) fiber is typically relegated to telecommunications runs, such as ISP feeds outside of a building. However, from time-to-time simplex fiber finds its way into applications where multistrand is required, either from damaged cable or a previously installed or mis-specified cable.

Each TL-1GSFP-BD includes two matching transceivers that feature a single LC connection. The transceivers must be used in pairs and are compatible with standard 1G network switches, media converters and other 1G-based IP devices.

For added versatility, the TL-1GSFP-BD is compatible with both single mode and multimode fiber. Single mode supports transmission distances up to 6.2 miles, whereas multimode supports transmission distances up to 492 feet.

Managed Print (MP) is a service that delivers self-service printing. MP allows students, staff, faculty, and other affiliates to print from any device and release their print to any support location using standardized equipment. Why use a managed print system instead of a simple printing system/policy? Costs related to printing have escalated over the years as more electronic resources are becoming available through the university's campus library's electronic resources, book publisher's websites, and other sources. To keep balance in the system by promoting responsible printing and to conserve resources by controlling abuse, waste, and rising costs, the university has implemented the user-friendly Managed Print Service as a cost recovery system.

Individuals using the MP are responsible for paying for the pages they print. Some campuses provide students enrolled for the current semester with a non-accumulating printing allocation/credit that they can use to pay for their print jobs. Staff, faculty, students, and affiliates can also use their campus bucks (e.g. WolfBucks, Bear Bucks, etc.) to pay for printing. Printing costs vary by type of printing (e.g. black & white, color), size (e.g. 8.5"x11", 11"x17", etc.), features (e.g. simplex, duplex, stapled, etc.), and the total number of pages. The MP stations will display the cost associated with each print job, and individuals must have sufficient balance available on printing allocation and/or campus bucks in order to cover the entirety of the cost. Please note that campus dining dollars are not usable for printing costs.

Purpose: Herpes simplex virus (HSV) and varicella-zoster virus (VZV) are neurotropic human alphaherpesviruses endemic worldwide. Upon primary infection, both viruses establish lifelong latency in neurons and reactivate intermittently to cause a variety of mild to severe diseases. Acute retinal necrosis (ARN) is a rare, sight-threatening eye disease induced by ocular VZV or HSV infection. The virus and host factors involved in ARN pathogenesis remain incompletely described. We hypothesize an underlying genetic defect in at least part of ARN cases. Methods: We collected blood from 17 patients with HSV-or VZV-induced ARN, isolated DNA and performed Whole Exome Sequencing by Illumina followed by analysis in Varseq with criteria of CADD score > 15 and frequency in GnomAD < 0.1% combined with biological filters. Gene modifications relative to healthy control genomes were filtered according to high quality and read-depth, low frequency, high deleteriousness predictions and biological relevance. Results: We identified a total of 50 potentially disease-causing genetic variants, including missense, frameshift and splice site variants and on in-frame deletion in 16 of the 17 patients. The vast majority of these genes are involved in innate immunity, followed by adaptive immunity, autophagy, and apoptosis; in several instances variants within a given gene or pathway was identified in several patients. Discussion: We propose that the identified variants may contribute to insufficient viral control and increased necrosis ocular disease presentation in the patients and serve as a knowledge base and starting point for the development of improved diagnostic, prophylactic, and therapeutic applications.
