本文簡(jiǎn)單探討了verilog HDL設(shè)計(jì)中的可綜合性問(wèn)題，適合HDL初學(xué)者閱讀 用組合邏輯實(shí)現(xiàn)的電路和用時(shí)序邏輯實(shí)現(xiàn)的 電路要分配到不同的進(jìn)程中。 不要使用枚舉類型的屬性。 INTEGER應(yīng)加范圍限制。 通常的可綜合代碼應(yīng)該是同步設(shè)計(jì)。 避免門級(jí)描述，除非在關(guān)鍵路徑中。

Tug of War(A tug of war is to be arranged at the local office picnic. For the tug of war, the picnickers must be divided into two teams. Each person must be on one team or the other the number of people on the two teams must not differ by more than 1 the total weight of the people on each team should be as nearly equal as possible. The first line of input contains n the number of people at the picnic. n lines follow. The first line gives the weight of person 1 the second the weight of person 2 and so on. Each weight is an INTEGER between 1 and 450. There are at most 100 people at the picnic. Your output will be a single line containing 2 numbers: the total weight of the people on one team, and the total weight of the people on the other team. If these numbers differ, give the lesser first. )

數(shù)字運(yùn)算，判斷一個(gè)數(shù)是否接近素?cái)?shù) A Niven number is a number such that the sum of its digits divides itself. For example, 111 is a Niven number because the sum of its digits is 3, which divides 111. We can also specify a number in another base b, and a number in base b is a Niven number if the sum of its digits divides its value. Given b (2 <= b <= 10) and a number in base b, determine whether it is a Niven number or not. Input Each line of input contains the base b, followed by a string of digits representing a positive INTEGER in that base. There are no leading zeroes. The input is terminated by a line consisting of 0 alone. Output For each case, print "yes" on a line if the given number is a Niven number, and "no" otherwise. Sample Input 10 111 2 110 10 123 6 1000 8 2314 0 Sample Output yes yes no yes no

The Audio File Library provides a uniform programming interface to standard digital audio file formats. This library allows the processing of audio data to and from audio files of many common formats (currently AIFF, AIFF-C, WAVE, NeXT/Sun .snd/.au, IRCAM, AVR, Amiga IFF/8SVX, and NIST SPHERE). The library also supports compression (currently G.711 mu-law and A-law and IMA and MS ADPCM) as well as PCM formats of all flavors (signed and unsigned INTEGER, single- and double-precision floating point).

2^x mod n = 1 acm競(jìng)賽題 Give a number n, find the minimum x that satisfies 2^x mod n = 1. Input One positive INTEGER on each line, the value of n. Output If the minimum x exists, print a line with 2^x mod n = 1. Print 2^? mod n = 1 otherwise. You should replace x and n with specific numbers. Sample Input 2 5 Sample Output 2^? mod 2 = 1 2^4 mod 5 = 1
