AN 775: Na-ewepụta data oge izizi maka Intel FPGA

Ị nwere ike iwepụta data oge mbụ I/O maka ngwaọrụ Intel FPGA site na iji Intel® Quartus® Prime software GUI ma ọ bụ iwu Tcl. Data oge mbụ I/O bara uru maka nhazi ntụtụ mbụ yana imewe PCB. Ị nwere ike iwepụta data oge mbụ maka paramita oge ndị a dị mkpa iji dozie mmefu oge imewe mgbe ị na-atụle ụkpụrụ I/O na ntinye pin.

Tebụl 1. Usoro oge I/O

Kwụpụ 1: Mekọrịta Flip-flop maka ngwaọrụ Intel FPGA Target

Soro usoro ndị a iji kọwapụta na mekọrịta ezi uche flip-flop kacha nta iji mepụta data oge I/O mbụ:

1. Mepụta ọrụ ọhụrụ na ụdị sọftụwia Intel Quartus Prime Pro 19.3.
2. Pịa Ọrụ ➤ Ngwaọrụ, ezipụta ngwaọrụ gị lekwasịrị anya Ezinụlọ na ngwaọrụ Target. Maka example, họrọ AGFA014R24 Intel Agilex™ FPGA.
3. Pịa File ➤ Ọhụrụ wee mepụta eserese / atụmatụ ngọngọ File.
4. Ka ịgbakwunye akụrụngwa na schematic, pịa bọtịnụ Ngwá Ọrụ Symbol.
   
5. N'okpuru Aha, pịnye DFF, wee pịa OK. Pịa na Block Editor ka itinye akara DFF.
6. Tinyegharịa 4 na ibe 4 ruo 5 na ibe 5 ka ịtinye ntụtụ ntinye ntinye_data, ntụtụ ntinye elekere, na ntụtụ mmepụta mmepụta_data.
7. Iji jikọọ ntụtụ na DFF, pịa bọtịnụ Orthogonal Node Tool, wee see ahịrị waya n'etiti pin na akara DFF.
   
8. Iji megharịa DFF, pịa Nhazi ➤ Malite ➤ Malite Analysis & Synthesis. Synthesis na-ewepụta netlist imewe kacha nta achọrọ iji nweta data oge I/O.

Kwụpụ 2: Kọwaa ọkọlọtọ I/O na ebe ntụtụ

Ebe ntụtụ akọwapụtara na ọkọlọtọ I/O nke ị na-ekenye na ntụtụ ngwaọrụ na-emetụta ụkpụrụ oke oge. Soro usoro ndị a iji kenye ọkọlọtọ I/O pin na mmachi ọnọdụ:

1. Pịa Ọrụ ➤ Pin Planner.
2. Kenye ọnọdụ ntụtụ na mmachi ọkọlọtọ I/O dịka imewe gị siri dị
   nkọwa. Tinye aha ọnụ, ntụzịaka, ọnọdụ, yana ụkpụrụ ọkọlọtọ I/O maka ntụtụ dị na imewe na mpempe akwụkwọ mpịakọta Niile. N'aka nke ọzọ, dọrọ aha ọnụ n'ime ngwugwu Pin Planner view.

   
3. Iji chịkọta imewe ahụ, pịa Nhazi ➤ Malite Nchịkọta. Onye nchịkọta ihe na-ewepụta ozi oge I/O n'oge nchịkọta zuru oke.

Ozi metụtara

Kwụpụ 3: Kwupụta Ọnọdụ Ọrụ Ngwaọrụ

Soro usoro ndị a ka imelite netlist oge wee tọọ ọnọdụ ọrụ maka nyocha oge na-esochi mkpokọta:

1. Pịa Ngwaọrụ ➤ Time Analyzer.
2. Na pane ọrụ, pịa Nwelite Netlist Timeing ugboro abụọ. netlist oge na-emelite ozi oge nchikota zuru oke nke na-aza maka mmachi pin ị na-eme.
   
3. N'okpuru Tọọ Ọnọdụ ọrụ, họrọ otu n'ime ụdị oge dị, dị ka Slow vid3 100C Model ma ọ bụ ngwa ngwa vid3 100C Model.

   

Nzọụkwụ 4: View Oge I/O na mkpesa Datasheet

Mepụta mkpesa datasheet na nyocha oge na view ụkpụrụ oke oge.

1. Na Time Analyzer, pịa Akụkọ ➤ Datasheet ➤ Akuko Datasheet.
2. Pịa OK.

   
   Akụkọ nhazi oge, oge ejidere, na elekere ka ọ pụta ìhè na-apụta n'okpuru nchekwa mkpesa Datasheet na pane akụkọ.

3. Pịa akụkọ ọ bụla ka view ụkpụrụ nke Rise and Fall parameter.
4. Maka usoro nhazi oge na-agbanwe agbanwe, kọwapụta uru zuru oke

Example 1. Ịchọpụta oge oge I/O site na mkpesa Datasheet 

Na ndị na-esonụ example Setup Times na-akọ, oge ọdịda dị ukwuu karịa oge ịrị elu, ya mere tSU=tfall.

Na ndị na-esonụ example Hold Times akụkọ, uru zuru oke nke oge ọdịda dị ukwuu karịa uru zuru oke nke oge ịrị elu, ya mere tH = tfall.

Na ndị na-esonụ example Clock to Output Times na-akọ, uru zuru oke nke oge ọdịda dị ukwuu karịa uru zuru oke nke oge ịrị elu, ya mere tCO=tfall.

Ọgbọ data oge I/O Scripted

Ị nwere ike iji edemede Tcl wepụta ozi oge I/O yana ma ọ bụ na-ejighi ngwa ngwa Intel Quartus Prime onye ọrụ interface. Usoro edemede a na-ewepụta data oke oge I/O dabere na ederede maka ụkpụrụ I/O akwadoro.

Rịba ama: Usoro scripted dị naanị maka nyiwe Linux *.
Soro usoro ndị a iji wepụta ozi oge I/O na-egosipụta ọtụtụ ụkpụrụ I/O maka ngwaọrụ Intel Agilex, Intel Stratix® 10 na Intel Arria® 10:

1. Budata ebe nchekwa ọrụ Intel Quartus Prime kwesịrị ekwesị file maka ezinụlọ ngwaọrụ gị lekwasịrị anya:
   • Ngwaọrụ Intel Agilex- https://www.intel.com/content/dam/www/programmable/us/en/others/literature/an/io_timing_agilex_latest.qar
