国产FPGA跨入28nm,意味着什么?

来源: 2020/3/30 浏览量:120 关键词: 国产fpga 芯片 紫光同创 IC

近日紫光同创广发彩票投注率先打响了国产28nm FPGA的第一枪,这是一个好的开始,也是一个较正面的信号。为什么是28nm呢?从90nm、65nm、40nm、再到28nm,FPGA可谓摩尔定律最坚定不移的"执行者"。FPGA进入28nm制程之后,不仅功能与整合度能超越传统FPGA,最重要的是,产品性价比也进一步逼近ASSP与ASIC。FPGA突破了以往功耗过高的问题,逐渐发展成为高性能、低功耗以及小尺寸的代名词。这让过去一直为ASIC、ASSP等核心处理器充当“配角”的FPGA登上舞台中央,越来越多的开发者对FPGA的青睐度骤升。

撬开28nm FPGA的大门

谈到28nm,不得不从国外的两大FPGA巨头开始说起。其实早在2010年开始,国外的Altera和Xilinx广发彩票投注就开始了28nm之战。2011年,这两大巨头,同时发布了采用最新一代28nm工艺的FPGA工程样片。自此,FPGA正式进入28nm时代。截止到目前为止,Xilinx的28nm产品仍然被全球很多客户使用。据推断,28nm FPGA产品至少有7-8年以上的生命周期。

被Microsemi收购的Actel也于2019年推出了28nm的全FLASH工艺FPGA,密度覆盖10K-500K LUTs左右产品,属于中高端产品。不过其产品相对较贵,新产品的推广在当前国产化大潮下可能不易。

国内方面大部分企业已开始了28nm的研发。紫光同创是国内第一家推出28nm FPGA芯片的厂商,其Logos-2系列产品PG2L100H产品密度为100K,采用28nm CMOS工艺制程,相对于40nm工艺Logos-1系列FPGA性能提升50%,总功耗降低40%。这对国产FPGA来说是一个好的信号,但有专业人士分析到,这只是FPGA高端产品“万里长征”中的一小步,硬件本身的性能有待验证,软件和IP还有很长的路要走。打个比方说,这个28nm 100K的产品就像制造出了一张硬弓,至于能不打开这张弓,能不能射,射不射得准还要看这个软件行不行。

除了紫光同创,安路和高云的28nm FPGA广发彩票投注也都在研发中,预计2020年均会发布样品,密度也是100K左右。而京微齐力预计将在明年推出22nm的系列化产品。业内人士告诉半导体行业观察记者,国内300K左右的产品预计都要在2021年-2022年发布。

据业内专业人士告诉半导体行业观察记者,当前国产FPGA仍然以55nm或40nm为主,而且密度较小,只能覆盖和替换Xilinx Spartan 6/7的低半段产品,而密度在50K以上的较高端产品量产时间均较长,主要是因为软硬件协同和硬件效能充分发挥需要非常时间和项目积累。目前国产几家FPGA厂商在研的产品都是28nm级别产品,有望在2年内实现对Lattice产品替换的全覆盖,以及Xilinx/ALTERA中低端产品的全覆盖。

Xilinx的Zynq 7系列,可以理解为在A7基础上加上ARM 硬核,A7内核+ARM Cortex A9单核(766MHz)或双核(866MHz),各有三个密度:23K/55K/65K, 以及28K/74K/85K。业内人士指出,目前国产FPGA尚无同类型产品面市,主要是因为ARM CPU软核的外设IP及软件的开发量巨大,设计难度也大。几年内恐难有与Xilinx匹敌的产品和软件平台面市。

“短时间来看,在产品方面,FPGA厂商需要尽快往高密度发展,但高密度需要大量资金以及客户试用、试错;在市场方面,随着国产化大的趋势下,国内客户也广开绿灯,这对国产厂商来说是一个很好的机遇,国内几家厂商在消费类、LED、工控市场要尽快有出货。”,知情人士强调。
