培訓(xùn)方式以講課和實驗穿插進行
課程描述：
HSIM是全球第一個滿足深亞微米設(shè)計需求的全電路、層次化的晶體管級仿真器。它可以準確的仿真電路的各種行為，包括：電路的功能、電壓和電流波形、時序和功率信息、電源網(wǎng)絡(luò)的電壓降、串擾噪聲以及地彈反射等。由于采用了創(chuàng)新的層次化數(shù)據(jù)存儲和同構(gòu)匹配算法，HSIM對仿真的電路規(guī)模幾乎沒有限制。層次化數(shù)據(jù)存儲免除了仿真器處理電路臃余單元和子電路對內(nèi)存的需求，因此HSIM可以容易地做到高容量的全電路仿真；同構(gòu)匹配可以減少對臃余單元和子電路的計算量。
HSIM為高級IC設(shè)計人員提供了一整套全芯片電路驗證所需要的功能，包括：?
·分級存儲：應(yīng)用高效分級結(jié)構(gòu)數(shù)據(jù)庫減少內(nèi)存使用量并擴大電路尺寸。?
·回歸模塊矩陣解算程序：采用分級結(jié)構(gòu)進行電路模擬，精度接近SPICE。?
·分級RC抑制算法：降低分級結(jié)構(gòu)電路數(shù)據(jù)庫中寄生電阻和電容的復(fù)雜程，減少精度損失。?
·布局之后寄生現(xiàn)象的后向注解：提供有效的布局后模擬和分析，存儲器需求少。?
HSIM可以向SPICE一樣用于任何電路的瞬態(tài)仿真，而且它比SPICE快無數(shù)倍。
HSIM的強項在于它維持高精度和快速的情況下，對數(shù)以千萬記的晶體管的仿真能力。
HSIM的用戶可以用它來對大的電路模塊、一組電路模塊或者整個電路做晶體管級仿真。
兩天的課程安排：
第一階段
HSIMplus platform overview
Software download and installation
HSIM input/output files
Basic HSIM setup
第二階段
Accuracy vs speed
Back-annotation
Interactive debugging
This training will teach you how to use the Synopsys HSIM FastSpice simulator. It will introduce HSIMplus, a comprehensive platform for simulation and analysis of high performance analog, mixed-signal, memory, and system on-chip designs including important post-layout effects.
The HSIMplus platform is built on the HSIM simulator to provide a fully integrated solution for nanometer IC design, including options for dynamic voltage drop analysis considering the timing impact of power net variation; reliability analysis of power and signal nets; coupling capacitance and dynamic crosstalk behavior; and MOSFET device reliability. Integrations with Cadence’s analog design environment and various HDL simulators, as well as circuit screening complete the set of available options.
