自動(dòng)售貨機(jī)設(shè)計(jì)VHDL代碼ISE仿真

名稱：自動(dòng)售貨機(jī)設(shè)計(jì)VHDL代碼ISE仿真

軟件：ISE

語(yǔ)言：VHDL

代碼功能：

設(shè)計(jì)內(nèi)容

在EDA環(huán)境下,使用VHDL語(yǔ)言設(shè)計(jì)一個(gè)自動(dòng)飲料售賣機(jī)

設(shè)計(jì)任務(wù)和目標(biāo)：

1.使用VHDL語(yǔ)言描述一個(gè)自動(dòng)飲料售賣機(jī),能夠接收5角以上10元以下共4種面額的貨幣,進(jìn)行飲料的購(gòu)買,并根據(jù)實(shí)際情況找零。

2.飲料共6種,對(duì)應(yīng)6個(gè)按鍵。飲料售價(jià)分為1元、1.5元、2元和3元,存在兩種或兩種以上的飲料對(duì)應(yīng)相同售價(jià)的情況。

3.編寫合適的 testbench文件,對(duì)上述系統(tǒng)進(jìn)行測(cè)試并仿真。

4.完成該系統(tǒng)的ⅦHDL模塊化描述,注意使用分層次設(shè)計(jì),并在頂層設(shè)計(jì)中采用元件例化的方式指定模塊間的硬件連接方式。
